Welcome Homer J! How are things in Cornwall?
YMMV - Your mileage may vary
FWIT - For What It’s Worth
IANAD - I am not a Doctor
WTF - What the Fuck
WTH - What the Hell.
ROFL - Roll on the floor, laughing.
ok thanks, thats useful, but what does SO mean, i keep seeing this everywhere and dont know what it means - search of? Special one? please explain!
SO = Significant Other (boyfriend/girlfriend/partner/whatever)
I hate the SO initials, because I worked in the juvenhile justice system for 7 years, and SO means something MUCH different there (sex offender ).
and even after all that time, I STILL misspell ‘juvenile’. :smack:
WB, Homer J. FWIW, I hope these lists of acronyms work out for you. IMHO they are fine, but I was ROFLMAO when my SO wondered WTF we needed a list for. BTW, these lists have been compiled over a long period of time so use them wisely and don’t be a PITA. Remember, BILC doesn’t meen you have to use them. YOYO and but YMMV.
