A nickname for 19 year old, south Florida rapper "xxxtentacion" (Jahseh Onfroy). In his first interview after being released from jail, he explains that the nickname refers to his penis size. He says the length of his penis is good (7 or 8 inches), but that the girth is lacking. He compares it to an E.T. finger. Despite this, he doesn't seem to encounter any sexual problems.
Me: I love X, he is my soul mate. I would do anything to be with him.
Drake: You wanna get with Young Dagger Dick?

Me: It's not the size of the wave that matters, it's the motion of the ocean. I wanna be his emo bitch.
