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.
