fuck-thirty 

An obscure measurement of time, really early in the morning or very late at night. Used to emphasize how incredibly early or late it was.

After the huge blizzard, my wife woke me up at fuck-thirty to go shovel the driveway.

Fuck-thirty 

Refers to a half-hour after sex. If you did your job right, your girl will still be clinging to you at Fuck-thirty, or if you did an outstanding job, she'll be asking for an encore performance around Fuck-thirty.

Jeff knew the deed was done right when his girl woke him up at Fuck-thirty just to say "I love you."

thirsty as fuck 

To be incredibly thirsty beyond belief and adding the word f*** at the end of any sentence is always okay to.

Oh my gosh this beer looks so good I'm thirsty as fuck.
