when a person of either gender pursues sex with another individual, and then ditches/dumps/leaves them after. Some people will lead the often unsuspecting individual into believing that their intentions are pure, or that they have feelings for the individual. This is often just a front to gain the trust of an individual. Do not fall for it.
I had unprotected sex with my boyfriend, and the next day he asked me if I bought the pill, then when I said yes he dumped me. Why did I ever fall for the Fuck and Chuck?
