Purge Job
A sexual act in which a woman or a man goes down on an erect penis, jamming the penis down his/her throat until he/she chokes on the penis and purges all over the penis and balls; following the purging, he/she proceeds to finish the man off with his/her mouth or hand, using the throw-up as a lube.
Becky and Bob took turns giving Rick a purge job, each enjoying the taste of eachother's green lube.
