Yah, there was a punk-ish Trenchmouth in the 90s from Chicago. None of us had heard of them before we named the band, and one of our members actually had trench mouth, so we figure we've got cred. I'm kind of conflicted on the name after learning of them, exactly because of confusion like yours, but I think we're the only extant band named Trenchmouth, so I deal with my conflict.
