D is for dumb, you're as stupid as can be

U are unimportant, you mean nothing to me

M is for your mother for not aborting you

B is 'cause you're boring, and I don't like you

D-U-M-B

You're so dumb

D is for your dad, 'cause he don't know shit

U is for your ugly face that I wanna hit

M is for your mouth, 'cause it never stops

B is for your brain, you're as dumb as a rock

D-U-M-B

You're so dumb

D-U-M-B

You're so dumb
