When your girl is riding you, she is going up and down on your dick and you about to nut. She comes down one last time hard as fuck and you cum and when she come down the last smack sound like a thunder strike.
When I was with my nigga last night he made me thunder clap.
When a male is performming a sexual act involving a woman's breasts as a form of masturbation while straddling her (also known as titty fucking), the male throws up on her breasts while at the same time farting (with anal leakage occurring, but not necessary) on her abdomen. Ergo: Thunder (fart), Mountain (titty fuck), chowder (throwing up).
Upon a very drunken evening, my room mate perfomed a Thunder Mountain Chowder on an excessively irritating, yet equally unlucky female necessitating her taking a shower and him washing his bed linens several times.
