Instahard

For a male penis to go from a state of softness or relaxation to a state of an uncontrollable erection in the penis.
Mainly caused by a beautiful or attractive female when seen or spotted with the eyes.

A combination of the words: Instantly (Without Delay or Immediately) and Hard (Not easily penetrated).

"Man, I just got instahard when she walked in"

"Lola Luv = Instahard"

Instafart 

A powerful fart, immediately filling the room with a terrible smell.

We were riding in the car and my wife let out an Instafart making it hard to keep my eyes from watering.

instabeat 

While playing Halo 3, you hammer on the "B" button to lay a melee smack down. At the exact same instant your opponent also hammers on the "B" button and you beat each other down. This is often followed by a "You asshole" as well as "instabeat"!

Joe - "Hey Bob did you see that we both beat each other down in Halo 3."

Bob - "Yeah that was massive INSTABEAT! you R-Tard. Did you see what I did to your sister as well?? INSTABEAT!"
