Idaho Summersault 

An act in which a person who has just completed sexual intercourse summersaults off the bed for no fucking reason

George: It's not an IOWA summersault; it's an Idaho summersault!
Grace: I don't care what it is; don't ever do it again

Summersault 

An unexpected heat wave that assaults a city and renders its people helpless.

Delhi was chugging along fine, waiting for the rains, when a summersault hit it with temperatures crossing 111 Fahrenheit.

epsom summersaults 

If a room smells funny and has been mysteriously been repainted (any colour from 'mission brown'to 'avocado green' {what have you been eating?}) this is probably because someone was using "epsom summersaults".
This is an play on words of:
Epsom salts - A diarrhoeic agent.
Summersault - putting your head between your legs and rolling forwards.
It is used to describe a mess left behind in a bathroom, where someone has missed the bowl, left a skid mark or generally left feacal matter all over the carpet, walls, roof, furniture, dog or anything not covered in cling film.

Leaves the same mess as a Di-hurl, although not in unison

1: I've just been to the dunny, I think someone has been doing "Epsom summersaults".
2: Well, it was one hell of a party.
1: It looks like the shit hit the fan... Literally

Laugh Out Loud (provided you don't have to clean it up.)
