mackshausted - when you're too drained or defeated to even think about girl

when you're too drained or defeated to even think about girls, like you just ran a marathon and got beaten up by a goat.

I got mackshausted after my dog ate my homework and my teacher gave me a D.

I saw a girl I liked and I tripped. I’m mackshausted.

I had to do 50 push-ups and I’m mackshausted.
