swingin' the bone

Masturbating, jerking off, wanking, beat off, toss off, whacking the chicken

"Oh man! I was swinging the bone all night, I barely slept!"
"Dude, you're totally addicted to swingin' the bone"

flippin' the biscuit

Poking casual and lighthearted fun at someone. Teasing. Joking

"Kid, there's no way you're natty"
"YOUVE GOTTA BE FLIPPIN' THE BISCUIT"
