A musical instrument which is played by expanding and compressing the bellows while pressing down buttons, keys, or a combination of both (depending on the kind of accordoin). The accordion has long received a bad repuation and been known as the worst instrument ever. However, the accordion isn't bad. It's just misunderstood.

Contrary to popular opinion, the accordion isn't only a crappy polka instrument. I can be sucessfully used in many style of music including: Cajun music, Zydeco, Tango, Irish music, and (surprise, surprise!) rock.
I saw an amazing accordion player today. He was really rockin'. But then someone came up and shot him in the head for playing the accordion.

The accordion is a sexual act in which someone receiving oral sex pulls out the ears of the person giving them oral sex, then hits the giver in the side of the face with open-handed slaps. The hand motion is very similar to the one used to play the accordion.
I don't like all the vallenato music Sandra listens to, but I do like playing the accordion on her when she goes down on me.
