Curfitzed

To ruin something funny intentionally, or unintentionally, but claim it was intentional to the point of cringe.

Whelp, you Curfitzed it almost immediately. Nice going Fitz...

Curtised

Trying to join in with an ongoing joke, however brutally massacring all the funny out of it in one fell swoop, destroying morale of all involved.

Yeah, we were having fun last night until Xeno curtised the whole thing. Fuck him.
