To Masturbate, and consequently ejaculate, in the shower while taking a shower.
Usually done in secret, to avoid detection of masturbatory behavior by others.
"I wouldn't go in that bathroom if I were you."
"Why not? It's dirty?"
"Timmy was in the shower forever...he was probably coca-blasting all over the place!"
