An OTTTB is an acronym for Over The Top Teeny Bopping. In simple terms, meaning a person who is a teeny bopper, but has taken it too far, and gone over the top.
OTTTBs, wear everything that is in their closet, that is in fashion to make themselves look in, buy the latest cds and basically waste their money on things that they don't need.
