“That stall blond (Bill) walks like he lost a pickle up his ass.”
From Thumper on Parole

Bill was boring as spilled sugar-free soda. Bill was like a stop-sign had a baby with a list of rules. If honkies was roads, Bill’d be a cul-de-sac blocked by a tofu store. Thumper got a eleven o’clock curfew when he weren’t at work, but Bill made Thumper go home by ten, so he wouldn’t “cut it close”. Don’t that make the curfew ten?
From Thumper on Parole

Thumper enjoyed touching a honky with nice little muscles and stall blond skin. Kinda light-skinned for a stall blond, but his blond hair was too dark to be a lightcorn, and it was in between straight and curly, which ruled out straightlane or raventack. Thumper know his honkies for real.
