Thunderclap

A thunderclap is when your girl is riding you and her butt comes down on your dick one last time and you nut. They call it the thunderclap for two reasons. That's the sound her butt makes when it comes down on your dick and when she thunderclaps you, you pass out and see thunderstrikes for like five minutes.

Guy 1: bro I was with my girl last night and she did the thunderclap on me. I passed out for like 5 minutes, crazy shit
Guy 2: bro what the fuck are you talking about

Todd

People talk about Todd a lot. You're gonna hear about at least 4 Todds in your lifetime, but here's the thing, you never actually meet Todd. Todd is real, you just can't meet him yourself.

Guy 1: I think I saw Todd at the store yesterday.
Guy 2: Who the fuck is Todd?
