Spitzenfreude

1. Taking joy from someone's downfall as a result of being caught in a sex scandal.

2. Regional. Taking joy from someone contracting a sexually transmitted infection.

Emily reveled in Spitzenfreude when her husband's dalliances left him with a crotch full of itchy crabs.

Feeling pleasure when leaving a washroom and you see someone going into the stall you just used.

Dave felt shitenfreude when he saw his annoying coworker enter the stall that he just dumped two pounds of Mexican buffet into.
