Noun. Once commonly used to refer to a band based from Calexico, California. Consisting of a mediocre singer, two Jewish guitarists, and a drummer (the normal one). The word was lost for several years when it inexplicably rose again on shirts. Since it was believed that the actual meaning of the word was lost, it was used to explain the state of being where one is completely embarrassed, but oblivious to the fact.
So me and her were at Elizabeth's party right? Well, me and her got bored, so we decided to go back to my place...and well she ended up giving me head completely naked on my drive way. I ended up cumming in her mouth, but that's not the great part, we went back to the party and we saw that one guy who likes her. So she walked up to him and gave him a kiss on the cheek. And I thought to myself "Mocos! He got bleu ruined!"
