Class blast

When in an attempt to hold on a fart while in a classroom (preferably during reading, tests, or other times when the classroom is relatively silent) the pressure between the butt cheeks increases vibration- effectively making the noise louder. A shocked expression is a sign of a class blast, while pure embarrassment is a sign of just a regular fart.

Student #1: "Yo, this dude let out a class blast right as the room got quiet in 6th period today! His face was the best part.
Student #2: "I feel bad for him, all he wanted to to was hold it in, tie he fucked himsekf over. Still funny as shit though!"

Knuckle Blasting

Getting a tattoo of letters on each finger (generally excluding the thumbs) in order to spell a word or words about eight characters in length. The tattoo goes between two knuckles per finger on the outside of the hand.

"I had a little knuckle blasting session last weekend at the tattoo shop. It says 'hold fast' because I'm a sailor."

When you smoke a joint, and there's only one puff left. The last hit of a joint.

Lateisha: ''Yep, pretty much. (*giggles*) You want last blast?''
