Your spleen 

The ultimate comeback to any "your mom" or "your face" jokes. It's power exceedes any other comeback and it can not be rivaled.

Tom: You suck ass!
Bill: Your mom sucks ass!
Tom: Well your mom's face sucks ass!
Bill: Your mom's face's spleen sucks ass!

*Tom gets served*

Cooked your own spleen 

"A well known expression for a newspaper closing" - David Mitchell

To put yourself into a unfortunate/self-damaging situation where the blame cannot be successfully shifted onto someone else i.e. Shooting yourself in the foot

Phil: Did you get to shag that slag from oceana?
James: Nah fam, got too wasted and passed out
Phil: You've cooked your own spleen, there!
James: I know, bruv

Mike G: Did you break up with Lydia?
Marcel: Nope. Told her I loved her by accident.
Mike G: CYOS.

Reginald Poshington: Hello there old chap! How goes it?
Rogers Chestertonmastercard IV: Not so well, I'm afraid old sport. I just heard back from the Regatta Club and it seems my work to further the segregation amongst the races within my rugby club, albeit a step back into the ways of the splendour of Uncle Adolf, served as a conflict of interests and hence they have heaved me from the running to become a partner. Daddy won't be pleased at all.
Reginald: Well then, old spice! You've cooked your own spleen, haven't you?
Rogers: In deed! This is TRULY a recipe for disaster
