The Jensen Effect 

A br0tal effect on yourself where you turn to drink, flatcaps, homosexual songs & dancing like a tard.
Another part of the effect is sitting up the back seat in the cinema and having nothing but banter & taking the pish out of the movie your watching.

I had the jensen effect last night, i woke with a hangover and im still laughing at Ginger Goats.
