This form of musical sexual intercourse is initiated as the male partner sits on the bed playing funky slap bass while the female services him with oral sex. During this time, the male partner typically says things like "Yeah, bitch I be gettin' ma funk on wid ma bass, now you be gettin' yo groove on wid ma jimmy."
As the man feels he is approaching his
orgasm, he will steadily increase the speed of his playing. Seconds before
orgasm, he will remove his genetalia from the female's mouth, cast the bass aside and instead proceed to slap her face with his
penis senselessly. In accordance with the fact that he is "slapping" with his
penis, he will also continue to imitate funky bass sounds as the
penis hits her face, to make it seem as though he was still playing. Typically, the male will say during this period "Ma dick be
tight, and so be ma playin', bitch!" Upon orgasm, he will lay down an even eruption of semen onto her face and exclaim, "Damn bitch, ya make ma playin' so
tight I broked a string." A period of role play will then ensue in which the male pretends to be a famous rock
star and the female a groupie who damaged his "instrument."
During a 1985 Van Halen show, bassist Michael
Anthony was reportedly seen by drummer Alex Van Halen as doing this to a
groupie named Gracia Barr. To all known sources, he invented this technique. The reason for this technique being known as "eruption" is because Van Halen has a
popular song of this name.
