Twitter, on account of the 140 character limit, encourages extensive use of shorthand typing. Most of these acronyms might be familiar to regular Internet users but some are very specific to Twitter.
Here is a list of top Twitter acronyms that we know so far.
RT = Retweet.
PRT = Partial Retweet / Please Retweet.
OH = Overheard.
DM = Direct Message.
@ : Reply to [username].
BTW : By The Way
FTW = For The Win.
FTL = For The Loss.
IRL = In Real Life.
FTF = Face to Face.
IMHO = In My Honest Opinion.
YMMV = Your Mileage May Vary.
BR = Best Regards.
b/c = because.
JV = Joint Venture.
LMK = Let Me Know.

IMHO is “in my humble opinion” IMHO. Never have I ever heard anybody say “in my honest opinion.”

One more I’ve seen used several times: HT or Hat-tip aka nod to someone or giving due credit.

“LOL” should be in the list?

IMHO=In my humble opinion. At least this has been the definition for the past ten years of online message boards.
I’ve also seen bc=because and F2F=face to face (like b2b=business to business).
I’ve sent and received tens of thousands of Tweets and I’ve never seen PRT, that’s new to me.

IRL = In Real Life
As in, “At the tweet-up all the tweeps can meet IRL.”

I guess PRT is such a short form that you yourself has created.
