When a girl in lululemons with a very nice ass walks past, and one becomes so hypnotized by checking them out that they dont watch where they are going, and usually end up hitting a wall. The luluhypnosis victim usually becomes so astounded that even though they know they're caught and look like a perverted idiot, they still dont stop staring.
Penny: OMG did you see Tom? he walked right into the wall and wouldnt stop staring at my butt!
Cassidy: Well you are wearing lululemons, he probably got a bad case of luluhypnosis
Jeff: Damn it Paul come back to us!
Ryder: Its no use, Jeff, hes got luluhypnosis
