Stay Puft Meltdown

The act of filling a woman's vagina with marshmallows. Then proceeding to fuck her until they get all melted and gooey, pulling it out and having her suck and/or lick it clean. This is similar to the melted Stay Puft marshmallow man at the end of Ghostbusters, just imagine the dick as the proton gun.

Dude Uno: I did the most awesome thing last night with my girlfriend!
Dude Two: Whats that?
Dude Uno: I gave her the Stay Puft Meltdown!

Global Meltdown 

When a person is traveling and they fall apart. This person attracts attention to himself or herself because they have lost their edge. Their friends flee immediately.

I am out of here. We are in Prague and Ryan is having a Global Meltdown and yelling at the nice waitress. Get him a broom to pick up his scattered mental pieces and have him call me tomorrow when he has his s*&# together. Unacceptable.
