Do you a solid

(noun phrase) 1. A deed done usually for a close/good friend and understood as a favor; 2. A compacted bowel movement free from any signs of liquification; 3. The production and further application of an impressively hard/erect penis/cock that is both visually and physically quality material and most pleasurable to the recipient.

Bartering on her investment and hoping to get a fair deal, the young lady got in on a sweet deal. She had ended her request with the well worn words, 'Can you do me a solid on that?" The voice on the other line, clearly Nikki's, told her in no uncertain terms, "Little girl, I'm gonna do you a solid, and then I'm gonna double it cause this needs to happen for me for sure. First off, the weight will be there---no worries there. That's your first solid, dig. The other solid, now speak now or forever hold your ankles high. I mean the other solid that'll be coming with the first one is this FUCKIN' rock-hard, totem-pole cock of mine that's practically ripping through my jeans right now at the thoughts of how I'm gonna whoop your ass when I put this cock to you. So dolid's being done for you tonight, twice guaranteed. If you require more...... ask. I'm heading in your direction now, girl".

Do me a solid 

The phrase "do me a solid" means do me a favor. The term was first used in the Northeastern United States, particularly in urban environments, at least as early as the mid 1980's, long prior to the Seinfeld episode usage.
