A phrase which can be used for comebacks when all else fails. No one else will know what it means, as it is a phrase born out of drug abuse. There is no one definition of trumpet buster, it just... is. Rumour has it that trumpet busting is a traditional practice of icelandic whores.

Letters of the phrase may be interchanged.
