When a girl is very horny, she might say "dick me down" and that means she wants you to fuck her so hard that she wont be able to get out of bed the next morning.
when you're ridiculously intoxicated and very horny. you must scream and sing this in different tunes. let the whole party now about your sex drive so you can get some mother fucking dick.
What a girl said is to you she wants you to fuck the shit outta her and not just regular sex that pornstar sex, that grip my hair sex and that aggressive sex.
