It can actually mean two things

A Smilie face, and a Straight face. But last time I checked this wasn't a Smilie topic.

What about sthu/shut the hell/heck up? I noticed that that one isn't on the list. I know all about it's more explicit counterpart, as somebody told me off with that once. Not on here, on Facebook. I didn't take it lying down. I fired back, but I don't remember what I wrote.

We could add it to the list, although there hasn't been any need to add it to the list yet. I'll add it to the acronyms not on the lists.

Here's one not on the list.

ETEG=Ear to Ear Grin.

Got two more here for you.
First one: PMP = Peed/pooped my pants (Ex. I laughed so hard at the comedy show I PMP.) (I actually heard comedian Bill Engvall use this term at a comedy show I went to last November. It was him, John Pinette, and somebody with Dave for a first name. Bill mentioned at the end of his act that he doesn't get texting, but he did come up with PMP and said something along the lines of, "If you tell your friends you went to this show, and ask how it was, tell them you PMP.")
Second one: AAS = Angry as s*** (This one I came up with myself after seeing a report on the local news regarding the killing in the line of duty of a Detroit police officer by a suspect who, according to his criminal record, shouldn't even have been out on the street. The AAS term was my description of how angry Wayne County Prosecutor Kym Worthy was over how someone with this kind of record could still be on the street. In short, she was AAS.)
