F'd up 

to have consumed an amount of alcohol in a short period of time which makes you say stupid shit, do stupid shit, and/or puke everywhere and pass out. This usually results with you waking up somewhere strange with a killer headache and overall having the time of your life.

Last night while i was f'd up I lost consciousness and this morning I woke up with a hangover and with no boxers on.

F.S.D. cover up 

A F.S.D. who starts a generic "hardcore band" so that they feel they have a right to call anyone F.S.D.

Will - That's a pretty obnoxious bow you have in your hair.

Liz - Yeah, but I like it :D

Will - Ya know, it's pretty F.S.D.

Liz - Ya know, not only are you THE biggest asshole I know, but you're also the biggest F.S.D. cover up EVER! So why don't you go suck off the people at Music at the Mall so you can play up there again. Cuz your music sure as hell didn't get you in up there.

F.S.D. cover up 

F.S.D.'s that call people F.S.D. for some bullshit reason to try and cover up the fact that they themselves are F.S.D.

Max - Do you like Chiodos?

Austin R. - F.S.D!!!!!!

Max - Wow. You have to be the biggest F.S.D. cover up of all time
