The act of two individuals rubbing pelvic regions against each other in order to cause orgasm (implied while wearing denim trousers). Similar to dry-humping and "OTPHJ" (over-the-pants-hand-job).
It was casual Friday when I walked in the middle school bathroom only to find my history and Spanish teacher jeanjerking in the handicap stall. Good thing I didn't come in a few minutes later to see the full-on OTPHJ.
