The aformentioned angry dolphin is not correct. The true angry dolphin involves normal sex, as in where the "hrum" is in the "vageen" (according to Borat), and the man proceeds to pull out and insert into the woman's ass. Angered, the woman responds with the yelling of "Enh! Enh! Enh! Enh!!!!" This is basically the sound a dolphin makes. Assuming the chic isnt into anal, she will emit this sound with much anger, but you'll probably do it anyway....because deep down she really wants it.

v. collectively or individually finding someone/something to blame for a problem, as opposed to brainstorming which connotes finding solutions to a problem

n. the act of finding someone/something to blame for a problem

While copulating a la doggie style position shaft at ladie friends anal wall and proceed to probe until met by a shrill 'uh-uh uh-uh' in a high pitched dolphin esque voice while she arches her back from the pain shaking her head.
