1. Sag their pants
2. Threaten to fight you like a man, but really mean, "come at me ese me and me and all my homies will fuck you up puto".
3. Wear bandanas to represent their homosexual gangs that they are a part of. Popular homosexual beaner gangs include but are not limited to: The Latin Kings, La Marasalvatrucha (MS- thirteen dicks up the ass), Mexican Mafia (technically beaner mafia), The 18th street gang, named for the eighteen gangbangs they hold every week, and many other faggy beaner gangs.
4. Have never opened a book.
5. Consider graffiti art
6. Think they are tough when in reality, they are too scared to fight you one on one and must call on their piece of filth "homies" to help them out in a fight.
7. Make the Catholic church look bad by thinking that it is ok to commit acts of robbery and murder while wearing a rosary or crucifix around their necks because it is part of "la raza".
Shawn: That's not a beaner, that thing over there is. (points to some retard on the corner in front of a liquor store trying to act hard)
Dan: Sigh... after meeting this Asian girl's parents, we can't go out anymore because her parents think I'm a beaner.
Kevin: Dudeee, do they know what a beaner is?
Dan: Apparently not :(
Look at that beaner showing off his fake Nike shoes that he probably bought from kmart after begging his mommy for a few bucks.
Beaner: Ay foo orale guey viva la raza homes, sur side for life ese!
Mexican: Were you dropped on your head? Does "sur side" mean going down on another man?
Beaner: Simon ese...
A word of caution. Don't let a mexican catch you calling him a beaner, even if he was just talking smack about you in spanish. If he catches you, you'll have to fight him.
(and his 12 cousins)
You can diffuse the situation quickly by offering a giant nike swoosh decal as a peace offering.
