When you shave your pubes and they are such a big forest that the razor (weed wacker) gets caught in your pubes and you have no other choice but to tear it off the crotch.
Becky, last night I had a pube weed wacker happen to me and now my crotch hurts!
A sex act that involves a ZZ Top level bush and a man well endowed enough to do the helicopter. The man then uses the helicopter to push the bush out of the way enough to find the promised land
When two gay men hang themselves upsidedown, (At last one man must have, extraordinarily, long pubic hair for this performance.) one man stays still (Upsidedown still, mind you.) and the other man does the helicopter and swings his penis on the other man's pubes.
Hey bro man dude, let's go back to my place and do the Australian Weed Wacker cause we're gay, and men.
