derfing

When a guy and girl are sexually intimate, the practice of the guy to alternate between bottom and top holes (anus and vagina). No particular pattern of action is required, and the switch-off can be completely random (ie: top, top, bottom, top, bottom, top, bottom, bottom, bottom, top, fist).

Create special patterns to signify festive or celebratory events and occassions; re-live these occassions through fantastic, nostalgic sexual practices!

Donnie: Tim was derfing Julie and covered her vagina with shit.
Darcy: Goddam! O_O

Derf

The number between 5 and 6. 1,2,3,4,5,derf,6,7,8,9,10. Most people forget this because Donald Trump just added it to the number system in September 2019. Only the Pre-K classes of 2020 will know of derf.

"OK class let's count those cookies! 1, 2, 3, 4, 5, derf, 6, 7, 8, 9, 10!" the teacher told the kindergarten class.

DERF

Stands for "disability exclusionary radical feminist". They're like TERFs except the exclude disabled people, including disabled women, from the feminist movement and believe disabled people are a burden and don't deserve right. They also believe that autistic men are trying to rape women because "they are all predatory". They don't seem to acknowledge that autistic or disabled women exist and very ableist, particularly towards people with mental or neurological disorders.

DERF: "Autistic men are all predatory, misogynistic incels who are abusive towards women and want to molest them! Disabled people aren't even oppressed and mostly choose to be fucking retarded anyway. What do you mean disabled and autistic women also exist?"

Actual feminist: "shut the fuck up and stop being ableist, you ignorant DERF".
