The official acronym for the 5 membered, party-hard group "The Fuckers Girls". Originated from the basement of KMed on the night of October 29th 2011, when a certain young man entered said basement with the ever classic phrase "HEY FUCKERS!" Let it be known that this young man was extraordinarly intoxicated. Strangely enough, most members had never hungout witch each other prior to that Saturday night, but were able to establish connections and strong bonds over alcoholic beverages. While the name uses improper grammar and can sound strange to those outside the group, all members understand the reference and may even stifle a giggle when the story behind the name is told. TFG reunites on a regular basis to "fuck shit up". Famous phrases from the group include "TFG is here to make a scene", "Tiger tiger rawr rawr" and "Will is a pussy!" TFG can also be used as a verb by the group as "TFG-ing" which means a night in which TFG reunites.
"Yo, did you guys hear about TFG the other night?"
"Yeah man, they're so sick."

"Hey Anna/KMed/Kmac/Sarah/Dev, are we TFG-ing this weekend?"
"Fuck ya we are!"
