Did you guys knew that various baseball terms are used as sexual slangs to describe the level of physical intimacy? It’s kinda cool, and here are the most commonly used ones:

First base -> French kiss
Second base -> Fondling boobies and genitals
Third base -> Blow job, cunnilingus, and licking out
Home run -> Sex

An easy way to remember this using four F’s: french, feel, finger, and fuck.
