A "Skunktail"(suppository pill filled with kief) laced with PCP, LSD, Roofalin, and over-the-counter laxatives. Rendering the victim helpless, paranoid, disassociated, and covered in feces. Spikers are used to achieve a drug facilitated sexual assault. Spiker became a household name when several Bathhouse visitors came forward in the mid 90's of being sexually assaulted.

It's also been known as "spiking" and/or "getting spiked".

Guy 1: Is he still shitting?
Guy 2: Hasn't stopped.

A "spiker" is a rogue pubic hair that takes on the persona of an extremely hard piece of cotton (or even fishing twine) that has set up house in the front part of your undies. And usually makes an appearance when one is in a public place. Creating an irresistible urge to scratch your groin.
John got a spiker while at the supermarker. Drove him crazy trying to scratch it without being seen.

There are 12 teenagers gaggling around the park after the government locked down the city. Fucking Curve Spikers. They definitely have parents that are Anti-Vaxxers/Flat Earthers for sure (Probably Karen, and Steve).
