Dachel
A dacheler is a person who's too smart to be mad at you, even when you're being a total idiot.
Dachel: 'He's a dacheler, and he's still smiling even after I called him a donkey.'
Dachel: 'She's a dacheler, and she's helping me even though I'm being a pain.'
Dachel: 'He's a dacheler, and he's still writing me letters even though I'm a total mess.'
