When one or more beta males that have a cult following to someone jerks them off in a conga shaped line, with one hand reaching forward and the other reaching backwards. The leader is the only one not having to jerk someone off
Dude 1: Bro those guys totally would lick the dirt off of his boots yo.
Another form of the ever popular, "circle jerk", where there are only two participants therefore forming a "line" instead of a "circle".
The two participants jerk-off together and when they have both completed the action, they have attained a "linear jerk". Although sometimes referred to as a "linear wank", in the United States it has been growing in popularity in dorm rooms everwhere under the term "linear jerk".
Eric and I were in our dorm room, and it was just us, so we did a linear jerk. Next time you should come and we can have a circle jerk!
