LAHF
Laugh At His/Her Failure is when you burst into laughter because someone failed so badly it’s like they were born to fail.
He tried to do a magic trick and it looked like a dog was chasing a sock. LAHF like you just saw a ghost.
She tried to run and tripped over her own shadow. LAHF like it was a horror movie.
He tried to make a speech and it sounded like a pigeon was talking. LAHF like you were cursed.
