"Prolly": intentional clipping or illiteracy?

I see it everywhere on the internet: “prolly” where “probably” should presumably go. Are people intentionally abbreviating/contracting “probably”, perhaps because the mistakenly believe that this is cute, or do they actually believe that “prolly” is a word?

Every single one of them are prolly illiterate. You should make a crusade of pointing out this gross misuse of the English language at every opportunity.

It’s a contraction, I’ve never used it in a proper setting.

Those peeps prolly don’t care about grammar as much as the average doper does.

The few I have regular online contact with that use “prolly, peeps” and the like know better, but just don’t care. They’re just doing what’s easiest to type. Such things are still much better than some of the IM speak I’ve seen while looking over someone’s shoulder.

It’s an approximation of speech patterns, like “gotta.” I know when I say “probably” it usually sounds more like “prolly” than anytthing else.

I hated “prolly” the first time I saw it.

Eventually laziness won out. I usually use it only when IMing.

I balance out the mystical karma of the universe by using probabably all the time.

Who can tell.

At work we talk about the “wrongosity” of a solution or the “approximatedness” of a figure but we call Playboy “Recreationlad” which is also the name we use for Sportsman. I’m pretty sure we all know it is a pisstake.

I’ve always read *prolly *as ironic. Everyone knows the word is probly.

Bolding mine.
“Are” or “is”. IANASA (smart ass) I really would like to know which is correct grammar.

True story.

My at-that-time girlfriend was a salesperson in a hi-fi shop (c. 1982). They were featuring a new speaker cabinet with speakers having cones made of plastic instead of the usual paper. She did a demo for a customer.

“These cones are a new material, they’re better than paper.”
“Really? What are they made of?”
“They’re polypropylene.”
“Well, could you let me know if you find out for sure?”

[hijack] I may be wrong, but I thought “prolly” was a British internet-ism. Does anyone know?

Shoot, don’t get me to lying. I’m going with “they are” instead of “one is”.

IANAEM (I am not an English major).

The subject of the sentence is “one.” The grammatically correct verb is “is.” One is. One of them is. Every one of them is. Every single one of them is.

Gracias.
