Orignally, a slang word for illegal alcohol during the years around the Great Depression
"Let's hoosh tonight after the party."
"Did you see her hooshes? Fuhhhhh, they were huge, like whoa."
"Get your hoosh over here, now."
"Oooooo! You're in for a hooshin' tonight!"
A hoosh is when a male is manually ejaculated. The term hoosh is also onomatopoeia as the imagined sound as ejaculate projectile soars through the air, just before it comes to rest on a nearby surface.
I was just home hooshing. I hooshed all over the curtain ... my bad.
