Group jerk 

When a group of males get together with the sole purpose to mutually masturbate and jerk-off together in the same room, car or outside area. This does not necessarily mean they are jerking each other off, or having sex, it could be a group of "straight" guys who get together to masturbate and cum. A group jerk is generally more than two guys (which is a jerk off bud). A group jerk or jerk off bud is also known as a form of male bonding.

"Want to join our group jerk tonight? We already have four others and there is space for two more".
"I never miss the group jerk with my classmates, it's more fun to watch porn with others".
"Mike has the best group jerks at his apartment, since he has the biggest TV and best porn subscriptions".

"We had an unplanned group jerk in the car after lunch today, Tommy just started stroking so we all joined in. Fortunately i had a cum rag under the seat but my car wreaked when we finally got back to the office".
