I loathe the word 'epic'. It is overused and annoys me to no end.

Squatch--how rude does that sound?

Pussy - I think it sounds way to pornish for my taste and I would much rather mine not be called that.

Stoked. Hearing that word makes me feel grouchy and violent. lol.

I also don't like it when people call cool or interesting things "sick." I've always thought that was dumb.

I hate when people say "yous," as in "yous guys" ....it's not even a word...

I can only think of two right now.

Dump - In the context of potty humor. Very crude.
Jacked Up - I always want to hand someone a thesaurus when I hear that.

The only one I can really think of is "jawn," since it's basically a stand in for any noun at all. It can make it confusing when you're trying to figure out if the "jawns" in question are objects or people.

I just hate bad grammar, in writing or speaking. I find myself rolling my eyes when people use "r" for are and other things of the sort. It does not take that much longer to type are.

"Minez" as in "give me that, it's Minez!" Ack, these were high schoolers, by the way.

I must say I'm guilty on "yous" and "yous guys," especially when I was younger. Living as a Brooklyn gal, that's the language. I hardly ever do that now.

"crucial"
Heard it a lot in middle school to the point that kids would try to use it in a sentence such as this.

"Her hair is crucial." No... sorry hun but that doesn't work yo
If it's used correctly I don't mind but as slang it annoys me.

"Brah" is another one. OMFG it makes me want to punch someone in their kidneys nolie. Uhhh

I don't know what else xD I tend to over use slang from habits formed running with crowds in "the hoods" of my city. =.= andd I abuse them sometimes. 'bro, yo, homie, man, dank etc etc'
I even use 'hella' sometimes (mostly when typing) xD hehhe I'm guilty of it |:

Edit: actually i'm guilty of a lot of things that annoy people in speech -innocent face-

I used jacked up, sketchy, shady, uhhh all kinds of terminology that has nothing to do with it's actual definition

I call shit 'fresh' or 'stale' >_> yeah just jargon picked up from being with people who use slang everyday and growing accustomed to using it to make myself understandable to them XD it makes for pretty interesting speech patterns

I hate the word fag and the word cunt i just think they are digusting words and used to be mean and hurtful
