Stacking Thirds 

When three men each have a third (1/3) of an erection, and combine their efforts to achieve one (1) full erection.

Damn Girl! My friend and I think you're kind of fine. When our buddy-who sort of agrees-gets here, we'll be Stacking Thirds to Folsom Prison.

Stacking Pussy

Stacking Pussy refers to an individuals inability to maintain a properly organized schedule of incoming vagina, and the subsequent need to then stack the pussy up somewhere. Originates from RubixxQube and the Top 40 Entourages song "Bitches on my Dick", in the phrase "I stack that scrilla and that pussy to the roof of my Tahoe."

Did you hear that Jamal was fuckin' his baby mama, her cousin AND that bitch from Little Caesars? Nigga be stacking pussy to goddamn high.

stalling 

when you are walking and someone in front of you is walking at a slower pace, but you can't pass them. So you're stuck behind them almost walking backwards.

I was stuck walking behind a slow walker. I could not pass her, people were blocking my way. I couldn't move forward, I was stalling.

Stalling 

When a person is embarrassed by taking a dump in a public restroom and hides in the stall until everyone else leaves the bathroom.

Did you notice that Doug finished taking a nasty crap in the bathroom and was stalling until we left?

Ed kicked the outside of the stall door in a panic, "Jim, come out! I really got to poo! Everyone knows you just took a nasty one, why are you stalling?"

sport stacking

An awesome sport where you stack cups up and down in a particular way. Only done by awesome people that have awesome speed, awesome hand eye co-ordination, and most of the time no life. The less of a life you have, the better you are.
People that can't do sport stacking just dis the people that can because they're jealous and claim they sped the video up.
Somebody that does sport stacking is called a "Stacker"

Stacker: My record in sport stacking is under 7 seconds!

Jealous guy: Yeah right, prove it

Stacker: Sure (does it in under 7 seconds)

Jealous guy: ...you sped it up.

stacking cake.
