Moffucked 

The end result of watching a 'last episode' of any TV serial written by Steven Moffat, owing to the impossibility, confusion and pure anger at very complex and brilliant plots. Especially when there is a sizeable gap between one episode and the next. Usually found in relation to British Television shows Sherlock and Doctor Who.

A: Did you see that episode last night? It was infuriating!
B: I know! My head's been totally moffucked!

Interchangeable with 'mind-fucked'

mafucka 

As said by J-Roc on "Trailer Park Boys", a mafucka is the urban bastardization of motherfucker (q.v.) however its use can vary widely, see example:

"Game's postponed because no mafuckas can go to Canadian Mafucka and get a new orange mafucka for $2.99 !?"
