Term used in hip-hop culture to refer to rappers who write/freestyle only focusing on the fourth bar of each quatrain, leaving the previous 3 bars with nothing interesting to say. DON'T RAP LIKE THIS, EVER, PLEASE.

The term's origin was invented in argentinian freestyle competition circuits, with many rappers maintaining this style of rapping. You can see much of this style being exploited in events such as Red Bull: Batallas de los Gallos and FMS (Freestyle Master Series).
Man, this four-bar is wack, he ain't rappin' about nothing, boring af.

Nah, I don't listen to rap that much anymore, everybody's a four-bar nowadays.
