Occurs when a female thrusts her pelvis forcefully and repeatedly into the face of someone performing cunnilingus on her, causing rapid collisions of her pubic bone and the muff diver's face (and thus crudely emulating a jackhammer). These violent collisions may result in bruising of the victim's face and, in particularly violent cases, broken bones. The Albuquerque jackhammer usually occurs inadvertently as a result of extreme ecstasy felt by the female, and in such cases she is either unaware of the violent motions she is carrying out or aware of them but unable to stop or control them. In rare cases an Albuquerque jackhammer may be carried out intentionally by a woman, usually to seek revenge on an ex-lover whom she has seduced into performing cunnilingus on her under the false pretense that they have become fuck buddies
. In such cases of revenge, the female will usually trap the unsuspecting victim in a headlock with her thighs, so as to enable a merciless rain of blows upon his face without him escaping.
"Jesus, John! Your face is so horribly bruised! What happened?"
"Well, I saw Sarah last night at a bar, and she came up to me and said she still had feelings for me and wanted to be fuck buddies. Naturally, I obliged, and the next thing I know she has me in a headlock with her thighs giving me an Albuquerque jackhammer! I was in the ER all night."
"Good God, man."
