A skinny girl that that deceptively packs a whole lot of ass that you weren’t aware of at all because you only viewed her from the front.
Derek: Yo did you see that new girl Taylor? She’s pretty hot right?
Justin: Yeah, but she’s too skinny.
Derek: Nah man she’s holding from the back trust me.
Justin: Shit your right. She’s fucking packing. Might have to ask her out just to see how that ass feels.
A derogatory phrase that embellishes the phrase "hold my nuts". By adding the "from the back", a whole new context is added to the situation. The individual is no longer standing eye to eye as an equal and merely offering a courtesy by bearing the weight of your tremendous jewels; oh no, said individual is bent over, embracing whatever emotions you intend to lay upon them, as well as, cradling your low hanging fruit in order to prolong the occasion. If I could describe this phrase in a single word, I would use domination, as the individual receiving said phrase is being described as the pinnacle of submissiveness.
(Look "fuck you" and "screw you" by definition imply you would like to partake in an act of coitus with said individual, however, both are used as a derogatory phrase to imply you do not enjoy said individual. A hate coitus if you will. This phrase takes it a step further. You are welcome.)
Reginald Booker Jr. : I must say, your jacket does not match your trousers, however, did you leave the house thinking that fashion choice was a bright idea?
Brad: Dude you tuck your shirt into your underwear and your tighty whiteys stick out sometimes.
Reginald Booker Jr. : *Scoffs* Why I never, I will be informing HR that I no long feel comfortable in your presence.
Brad: Hold my nuts from the back, Reginald.
