From Colorado originally. That’s what my granma (from Nebraska) called them, ergo it is the correct term. 
I always do it.
On a somewhat related note, not long ago I bought a really green bunch of bananas. Left them sitting for days with no obvious change, thought maybe they had been picked too green and maybe the skin color would never change but the inside would ripen. Broke one open and it snapped like a crisp apple and a small taste showed it was bitter. Tried it again a few days later with the same result. Thought that maybe I should just throw the remaing bananas away because they would never be ripe, but they finally ripened after three weeks.
I believe the proper term is hammock of bananas.
I also took the question literally. Never heard of the term.
But no, I wouldn’t think it weird.
I’ve always seen a bunch of bananas, as in the type on display at a grocery store, described as a “hand.”
Buying individual bananas in the way the OP described is no different from people choosing apples or oranges out of a bin, when they are charging by weight.
I thought you were playing some kind of banana poker. Getting dealt a good or bad hand of bananas…
Three of a kind… 
If you just pick up two joined bananas it’s Texas banana holdem.
Put an Apple with them.
Anyway, there were four kids and we were living in the tropics: Dad brought home a /bunch/ of bananas. A Banana ./bunch/. A stem with a flower, that he hung under the stairs. And we picked the /hands/ as they ripened going up the stem (up? down? I can’t remember).
That’s how you get a supply of ripening bananas
Whatever you do, do NOT Google that phrase :eek: 
Will an iPod work or does it have to be at least an iPhone?
Wow. I just buy some bananas. I eat one, my gf eats one, the bird eats one. If any get too ripe I peel, halve, baggie, and freeze. Frozen bananas get used in daiquiris or smoothies.
Overripe bananas are perfect for peanut butter & banana sandwiches. Squish and lightly mix with a fork. Spread on two pieces of bread. I prefer my bread toasted. I brought one to grade school in my lunch box for many years.
I buy a full bunch of green bananas. We easily finish them before they go bad.
A guy like me from a northern country (well, he IS me) would be surprised to learn that bananas grow “stem end down” (it’s not really the plant’s stem of course). It appears gravity-defying-ish, if you’ve never seen the plant they come from. (I haven’t seen, I just have this isolated fact in my head that says “Heh. Bananas grow ‘the other way up’. Who knew?”)
So, it depends which way they were hanging, under your stairs.
One place we go to has large signs saying you can’t split up bunches at all. So if you want 3 and there are no 3 or less ones, tough.
Our solution: stick the remaining ones in the fridge when they get ripe. Where’s my Nobel Prize?
What is the penalty for unauthorized bunch splitting? Do security guards drag you out the back and beat you senseless with cucumbers?
I’m always worried about breaking rules and norms. For years I bought a small bunch and waited for them to ripen the way I like it. Then the last couple would be overripe or get thrown out.
The past year or so, I started picking out single bananas from the ‘loose banana’ pile. I’d try to get different ripeness bananas from there. After awhile, I think I saw someone breaking off bananas from different bunches so I started picking single bananas off of bunches. I’d pick a banana here and there, trying not to leave small bunches of 2 or 3. I suppose there’s a demand for small bunches, but it didn’t seen right to do that somehow.
I eat one with breakfast every morning, so I try to buy 7 at different stages of ripeness. I don’t break up existing bunches but there are usually plenty of singles laying around.
From the thread title, I too thought that you were doing some weird sort of banana art. (By the way; you misspelled weird.)
Personally, I call them a foot of bananas. Okay, not really. I call them a bunch.
They send the Hot Cops after you. And a construction worker.
