a diss. some say its really lame and when people can't think of something better to say. this is true sometimes. however at other times "your mom" disses can be really funny.. if it's the right person delivering the diss.
Laura: u know ur house sucks, we should go to mine.. i have Jumanji on DVD.
Rebecca: ur house smells like hot diareha.. plus Jumanji sucks more than ur mom when she was pregnant with u.
