Doc Browning 

A sexual scientific act in which one party peers into the anus of the other individual. This is done with either an empty paper towel roll or preferably a plastic table matt which is rolled up and inserted into the anus. When performing this erotic nerdy act please try to make mention of giggawatts in some regard or you can literally quote Doc Brown and say "If my calculations are correct, when this baby hits 88 miles per hour....your going to seensome serious shit"

Chelsea wants to get her Doc Browning on but hates all the Tinder Douche bags. Chels will probably just Doc Brown herself .
