Cuckoo 

Verb - to forcefully and without consent seal the genitalia passageways closed on an unsuspecting victim. Best results come from using medical grade, thin viscosity adhesives allowing an injection of glue deep into the genitalia cavity for an optimal, leakproof seal.

I was left with no other choice than to follow that wrinkled old bitch home, throat punch her sleeping husband to prevent any interruptions to the procedure, and then I performed a flawless cuckoo in that dumb hags dusty cunt bag. Cuckoo mafucka!!!!!!

Cuckoo poo 

When someone is passed out or asleep and someone else pulls down their underwear and takes a shit in it before pulling the underwear back up so when they wake up they think they've shit themselves. Can also be done in their bed.

My lightweight mate crashed out after some beers and luckily was face down on the sofa, too good an opportunity to miss. I had a turd on the cusp so pulled his kecks down and laid a cuckoo poo in them. I then pulled his pants back up and smothered it in before slapping him awake shouting 'you dirty bastard, look what you've done, you've stunk out the room!!". Mortified he didn't show his face for a while and still thinks my cuckoo poo was his.
