Originally derived from the
root word Tool. Over time the level of idiocy of the person being described forced the word to evolve into tool
shed, meaning a complete d-bag. On those rare occasions when someone is the ultimate D-bag, they are to be called a Tullah Sheddah or Ultimate Tool. Abbreviated versions
may include simply calling someone a Tullah or a Sheddah.
Nick saw that
Jed recently spent $500 on Dungeons & Dragons
gear, leading him to reply that
Jed has become a complete Tullah Sheddah.
