A super-pleasant activity --- usually performed as a playful farewell gesture --- whereby you smilingly extend one hand at a time to the other person, then firmly bob both his hands up and down once.
The 1-2-3 handshake is most often administered by a mushy-hearted guy to a pretty girl whom he's met for the first time; it's a way of showing that he really enjoyed the "sit together awhile and chat" session that she shared with him, and hopes that they can continue their friendship for the foreseeable future.

When 3 men - or women with penises - all lie down and suck or jerk each-others cocks in a circle-like position. The natural evolution of a 69.
"That party was wild!"
'What happened?'
"We got so high, we ended up giving each-other the 3-man handshake!"
'Bro, that's some crazy shit.'

To take something meant to keep you partying all night long, go it hard as fuck for 3 minutes and proceed to pass out for 4 hours while still wearing training wheels. Can also include finishing a dj set and in the final 3 minutes proceed to pass out by face planting on the turntables.
Potter popped, and 3 minutes later asked for a quiet place to sleep because he would wake up when it kicked in. 4 hours later he woke up still wearing his training wheels. Man that dude knows how to rock out a 3 minute rage.

A pseudo-punishment used by the hicks who run Williamstown High School in Southern New Jersey, USA. The "punishment" is given for many different reasons, but they all lead to one stupid result. The punished is to remain at home until 2:30 where they then must report to school from 3 to 7 o'clock and do assigned schoolwork from their classes. The only loop hole is that kids will still go to school that day or not come to school at all so their 3 to 7 turns into an expulsion and they get a free vacation. Sure you'll miss out on your dances and 3 school trips but the only thing that matters is Disney anyway, the prom is a hilarious excuse anyway because 9/10 you'll get mugged because it's Atlantic City.
TEACHER: You were caught smoking outside on the school grounds Jerry, that's a 3-7 for you.
Jerry: Your husband doesn't love you, does she Karen..?
TEACHER: No.. Jerry he doesn't..
Jerry: Your husband doesn't love you, does she Karen..?
TEACHER: No.. Jerry he doesn't..
