That does sound nasty. On the other hand, I’ve been known to eat Saltines spread with a thin layer of mayo. It’s salty, greasy, tangy, delicious!
I’ve had many people tell me that frozen pizza, dipped in salad dressing, is the best thing ever. Personally, I don’t give a damn if it tastes like heaven, that’s still just a weird thing to do and I’ll have no part of it.
White rice covered in grape jelly.
A drunken friend of mine in college ransacked my cupboards looking for anything to eat.
He ended up with canned sweet corn topped with Manwich sauce.
What, you mean just like Belgian-style Pommes Frites? Your definiton of “weird” is weird, or at least pretty parochial.
I’ve mentioned it before, but:
Calamari chips.
Think potato chips, except made from squid.
Also, they smell worse than tear gas.
Once I was at McDonald’s and a woman and her son were standing at the condiment station. Kid was about 4 or 5 I’d estimate and the mother was holding an ice cream cone. She asked him if he wanted butterscotch on his ice cream. As he was nodding his head “yes,” I was thinking, “Wait, there’s no self-serve butterscotch at McDonald’s…” then I watched her squirt sweet and sour sauce onto his ice cream cone and hand it to him. He seemed to enjoy it, so go figure.
One of my friends’ wife used to eat spaghetti sandwiches. Not that it tastes bad, but it just seems unnecessary to me.
Myself, I like cream cheese with my Fritos. It’s something my parents did, and for a very long time it was the only thing I actually used cream cheese for.
On a dare from my brother I cracked two eggs into a glass and drank them down (ala Rocky). He nearly puked. This was 2 years ago, not when we were kids.
Scrapple. shudders
Ron Jeremy.
Naw, just kiddin’.
Gefilte fish.
Want. Now! Get in my belly.
Of course I’ve spent almost two decades trying to find some more squid jerky.
I had a roommate in college who tried to throw dinner together one night from whatever he could scrounge in the kitchen. The result was some weird casserole made with spaghetti, canned salmon, and cream-of-something soup, topped with cheddar cheese. No he was not drunk, and no it was not good.
Pickles and Maple Syrup
If my gf is drunk, she often mixes mashed potato flakes with some cold milk and eats it before bed.
In fact, that’s the only reason we have a box of those flakes in the house.
Now, I eat those. I don’t understand why everyone doesn’t eat those! 
My father would do this, but with slices of banana.
I’ve done similar things back when I was poor and trying to teach myself how to cook. A particularly memorable casserole included canned asparagus, which is horrendous all by itself, but when cooked as part of a casserole it completely disintegrated and turned the entire thing a sickly bilious green.
It was also not good, but I had no choice but to eat it.
Miss Mapp, do you mean mayo and banana sandwiches, hold the peanut butter? I had forgotten my grandma used to eat those. Blech!
I’ll say. I’ve done what the OP shudders at many a time. Although what will make most people ralph is that I prefer Miracle Whip to mayo as a dip for Fritos.
I’ve seen people eat fries with mayo plenty… it’s still really weird.
Though I also think that people who like putting maple syrup on their bacon are weird too.
