Despite what people may think, this is not inspired by or at all related to the name of a human being.

L Tarnoff Syndrome is a marijuana/hallucinogenic toad related disorder, which causes it's victim to do a number of stupid things.

A list of these actions includes:

-Going to their "friend's" house uninvited.

-Having no train of logic.

-Attracting the opposite sex for no reason.

Many children are being born with this syndrome, and it is being linked to the licking of hallucinogenic toads by the parents.
You see that chick? Yeah L Tarnoff Syndrome for sure man. *some idiot drools*
