This New Year's Eve, I went to my sister's friend's party with her in New York. Right outside, in Central Park, was an anti-Trump protest. Several of her friends stood at the window and chanted "Protest! Protest! Protest! Protest!" really loud, then collapsed laughing. I just muttered, "I'm sure they heard you." Cue my sister and her friend laughing their asses off and I'm just sitting there, like "huh?"
Then fast forward a few weeks, my friend and I are watching a movie. In one scene, a guy is confessing that he cheated on his wife. Right as he says it, some random woman outside (who probably didn't hear us) goes "*GASP!!* That b***h!" I ... couldn't even. We had to pause the movie so I could finish my 15-minute laughing fit.
I just call it "stupid humor"
