Act of male masturbation, can only be performed by circumsized men. Where the masturbation becomes so vigorous and violent that the hand actually hits the testicles while stroking the shaft.
I went to sleep and woke up and my friend Billy was "hitting the sack" next to me wearing nothing but a lamp shade over his head.

A term used to tell a person to do something or leave a certain place. This term was first developed when a super scientist changed the channel, which his grandson was watching, on the television.
Son: Hey! I'm watching TV!
Grandfather: Hit The Sack Jack!
Son: I don't know if i should ask her out Rick.
Grandfather: Hit The Sack Jack!

A declaration used in parting from company when one is about to retire for the evening to sleep, but not before masturbating.
In delivery, there should be a slight pause between "sack" and "and" to emphasize that what was implied by the first statement was not what was actually intended.

Me: Well, guys... I oughta be getting along. Time to hit the sack... and then... go to bed.
