The chastity orgasm. Usually involves bringing a horny drunk girl back to your apartment, but rather than perform the conjugal act, you bore her into leaving by discussing sports, philosophy, or Scotch. This makes a girl "go", as opposed to "come".
Yeah, last night Hunter totally brought this sorostitute back to his place and gave her a chastigasm. She wanted his bod, but he gave her a lecture on Carl Jung instead.
