Cave whistler 

A usually large lesbian that eats more pussy than 20 fat girls eat chocolate. They're known to sport big tattoos & wear men's muscle shirts

Check out that cave whistler over there. I bet she eats more pussy in a weekend than the four of us eat in a year.

Whistling up a pig’s ass 

This expression was originally by Rednecks in the USA, but achieved wider recognition and usage due to combined operations between the US Army and British troops. It is used to describe something that is totally futile, a waste of time and effort and something you do not wish to do. By extension it can also be used to mean a person who is a waste of time and resources, someone with whom you do not wish to associate, that the world would be better off without and who is one of nature’s biggest mistakes, in short a complete and total Malcolm.

Malcolm has just fucked the system again, that waster is no more use than whistling up a pig’s ass.

Whistleswitch 

Take one thumb, stick it in your mouth. Then take your other and stick it in your ass. When I blow a whistle, switch thumbs.

Can girls play whistleswitch?
Fuck no. Now go play some whistleswitch, Austin.

Whistling Busker 

Hiring a prostitute to whistle 'Rivers of Babylon' up a mans anus, whilst jiggling his balls like a coin bag.

"I'll take a 'Whistling Busker' please."
