a der
the laugh of a magical, overly dramatic, pink-haired teacher who thinks she's the only one who can do it
"She laughed like Umbridge when I told her I flunked math.", and she cried.
"He screamed like Umbridge when he saw his dog dead.", and the dog was just sleeping.
"She did a der like Umbridge when she saw her hair fall out.", and it was a total shock.
