hot bunking 

is a common practice (often found on board naval submarines) where several people share the same bed. When the next person swaps out for work, the person laying down finds that the bed is still warm from the prior user, hence the term hot bunking.

I hate hot bunking with you because you smell.

Hot Cross Bunning 

'Hot Cross Bunning' is a sex act in which two gentlemen simultaneously ejaculate across a lady at perpendicular angles (an X shape).

The aim is to make the lady resemble the traditional Christian Easter snack, the Hot Cross Bun. Aesthetically this works best across the buttocks.
A subsequent sprinkling of raisins or currants is optional but encouraged.

We celebrated the end of Lent with a spot of Hot Cross Bunning

Hot-Dog Bunning 

Hot-dog bunning is when you stick your dick in between someone's ass cheeks so it looks like a hot dog in a bun.

I was fucking a girl and I wanted to surprise her afterwards, so I squeezed my dick between her ass cheeks and took a picture. She said it sorta looked like a hot-dog. Hot-dog bunning has become a running gag in our house now.
