Rocket Smash

When you're smashing your girl (or guy) so hard that you explode and take off like a rocket and it takes you to Mars.

Guy 1: Bro I just Rocket Smashed my girl last night that was crazy.
Guy 2: Yooooo no way that's crazy!

Brown Rocket

It's pretty self explanatory… firing a rocket and coming out brown…

Pretty much when you fuck a butt hole and you pull out and you have shit on your dick.

Bruv, I gave that chick a hell of a brown rocket last night!
