My mouth tastes like blood I've got a canker sore And goddamn does that shit hurt! It grew from one to more So, I'll pour a cup of water, and I'll add some salt And swish that through my mouth Swish, swish, swish, swish, swish, swish, swish! ♪ You're like a canker sore You never really leave Just when I think that you're gone You come right back and you attack me And so, I'll make your poison and swallow it down And hopefully that keeps you away for now ♪ Because with every word that I speak You make me cry out in pain My friends all know that I can't eat And I've gotta try and explain That it's all because of you You'll never leave me, will you? You're like the canker sore Underneath my tongue You're always buggin' me I've been this way for months Oh, but one day I'll beat it One day I'll defeat it 'Cause I don't need this I don't fucking need this (Hey, hey, hey, hey, hey!) (One, two, three, four!)
