1. Inhaling a joint or spliff with one of your nostrils and exhaling with your mouth.
2. That thing Charlie Sheen did in his tweet video when he went officially crazy in 2011.
Allie: Here hit this, but do a Nose Dive.
Cassie: Holy shit, that is so crazy.
Allie: That was a huge hit too.
Cassie: Yeah I didn't realize how big it was. And now I'm super high.
