Can be used in many instances. Bowed up ususally refers to someone or something being large, but can also refer to the positioning of something, or to describe things in abnormally large numbers.
That guy is bowed-up. Man I went to the club, and it was bowed-up in there. Dude, Matt is bowed-up on the toilet. We had six people bowed-up on that truck the other night.
