A weird version of an orgasm that is just... weird. Made up by (former? current? I dunno) Twitch staff member FerociouslySteph, who apparently thinks she's a deer.
"How's it going, littlebubby?"
"OMG this deergasm is so good!!1!1" *cums*
"...It's hunting season."
When somebody uses the term "deer" or any other redneck term, any redneck hearing has 5 (or more) orgasms at once. This produces a sound much like a muscle spasm and may produce saliva of the mouth. Sometimes the redneck will get mad, and kidney punch you, in which case respond with a kidney block.
Person A: "I just shot a tenpoint deer last wednesday."
Person B: "DEER!!" (has deergasm)
Boys who enjoy yaoi (a genre in Japan that contains sexual and/or romantic relations between two men); literally translates to "rotten boy"; corresponding female : fujoshi
