look up any word, like plopping:
basically longdicking is when you fuck a bitch. the one distinction between plain sex and longdicking, is that when you longdick, theres a certain special something sex doesnt have..usually a giant cock or an extreme amount of stamina.
I picked up some girl at the club last night and i was longdicking dat ho for like 3 hours straight till she passed out.

I was going all the way in, and then I would pull it almost all the way out before re entry. She was like..."Damn baby, I like that longdicking"
