To masterbate with a wacking motion, to Megan Fox with a poster of Jessica Biel on the wall. While listening to the Wezzer song "Why Bother" and talkin dirty while biting your lower lip.

When a young associate at a law firm sucks up to a partner.
Her partner wackin is getting a little out of control. She has to pretend to agree with everything the partners say and she buys them wine and new shoes all the time.

Used to describe when one is sitting around doing nothing. Usually in reference to masturbating. Stroking the cock, massaging the giggle stick, getting your groove on with your hand, flicking the wrist, masturbating.

when he whips it around in the air before sex. he slaps your face with that shit & slaps your ass. it stings against your skin & he groans when they collide. after being whipped around for so long his cum gets all creamed up in his nuts like every little sperm cell was just vibin' in a blender gettin' all creamy. he shoves that shit into your drippin' grandma cooch & it burns. no lube, just straight & dry. you share stds for hours & hours. at the end of this kind of sex you'll insides will be so stirred up & creamified, you will never be the same. & that bitch will have a road rash on his dick for years.

Wackin in the shack was fun for a while, until my dad found out and started doing it with me.
