I just ran into a couple of boosters on Supply Raid in Bill's Town. Parties Allowed.
One was dumping mollies and bombs 5 feet from himself and the other was bandaging. After sitting there watching this happen three times, I proceeded to teabag and then gave their position away by running and shooting next to them. Luckily the enemy were pretty good so these boosting idiots got killed. Then within 10 seconds I was "kicked from the match".
Rest assured, if I catch you boosting I will mess up your game. You cheating scum.
He got downed. I revived and healed. He got downed again. I revived and healed. I got like 2000 parts In the duration of a minute

Its when a team continually hurts themselves on purpose with bombs or mollies. Then a team mate gets points from revieves and healing. They do this in order to get lots of points.
One use boosters are there to be used.
