When one takes a hit of marijuana so large the resulting cough sounds as if one is participating in the breakdown of a mid-1980's rap.
"Dan hit that J like it was 1986 - started beatboxing."
"That bong hit made Dan sound like he was recording an album with Doug E. Fresh he was beatboxing so bad."

When your talking casually and you fuck up on what your saying, such as miss pronunciation, or just forgetting what the fuck you were talking about, and you continue the sentence with beat boxing noises, and random letter repetition.

An annoying co-worker who makes dumb sounds or mumbles phrases to themselves. (Known to be even more annoying when they do this while entering your office or when you walk by their desk, in a lame attempt to catch attention). Calling them a beatbox allows you to talk about them in public and makes people think you are discussing american idol.
NP: "If beatbox makes one more sound today I'll flip out!"
HW: "No shit, me too."
Beatbox: (enters convo from eavesdropping, a common trait of a beatbox) "Hey, you guys talking about idol last night? That's the best show ever..."

Yea-no you can't beatbox. It's just to dang hard. I mean, if you keep at it you might be able to do beatboxing.
