Gay slang:

When a man fucks another man up the arse so hard that all that comes out is farts. Essentially milling for wind, or 'Wind-milling'.
'Oh my gard, i got totally wind-milled last night, noisy as fuck'

'Are you going to wind-mill me tonight babe?'

'Who's up for some wind-milling? I've got the equipment, just need a suitable cavity'

Get the Wind-milling mug.
ogling a womans ass, ogling a womans bottom

Either:

a) Admiring a hot ladies bottom from afar (to Ass-moo) with obligatory 'mmmm' noises.

b) A group of men admiring the same hot ladies bottom and subsequently following her like a kine of cows, occasionally making subconscious grunts. (Ass-mooing)
Check him out ass-mooing that girl over there

Dude, we were totally ass-mooing that girl just then

One sec, just in the middle of an ass-moo, right she's gone now, what were you saying
