These bad douches are individuals who bang fat chicks and have no taste in women or game to secure them.
Also an individual who complains about not getting invited to a party and gets pissed off at his friend who was courteous enough to ask. All because the host said no.
A douche is an immature and dishonest individual that claims to be using his own original material that he came up with when attempting to game a girl, when in reality, he is using the same phrases that he learned from the guy that taught him everything he knows about gaming chicks.
A Levin does not have the skillz to treat the orifice of a sufficiently attractive female with his small reproductive organ.
"Only a Levin could have that many girls call him a creep."
"Wow man, your failure to get that girl was epic, you're such a Levin."
A man has 200 dollars clearly visible in his wallet and his part of the bill is only 5 bucks and says, "Uhhh guys...I don't really have much money right now, could you cover me?" and never pays the person back has just pulled a Levin.
