Both are expressions if you were drunk and did somethng really stupid. Namend after Sebastian Mohr, who did stuff like:
-burnin his house
-gettin hit by a car
-fell asleep next to his dog

Person1: Damnboy, you were really drunk last night!!!
Person2: can't remember shit
Person1: man you really were a mohr last night! You fill in some embarrasing or stupid action
2.)
When i came home last night i really made a mohr out of myself when i felt down the stairs.
