an impulse can used by a girl for self pleasure. This act is usually performed on webcam to an unknown viewer. The can is inserted in any hole availble even the mouth once it has been in the pussy baby!! Objects are then used after this for even greater plesh including; hairbrushes, larger cans, dildos and arms (the girls own)

A Drum and Bugle Corps that is ranked highly among it's competitors. It has a good reputation as one of the most badass Crops out there. They have a fantastic style of marching and musical quality better than many other Corps. Their outfits are far superior, featuring a baseball cap, this is what sets them apart from far less superior bands.

Everything above is bullshit, Impulse SUCKS. They wear fucking BASEBALL CAPS!!!
"Impulse? Those are the faggots who wear caps right?"
