A derivative of shwasted and smashed, shmoosted is the process of becoming severely inebriated from the consumption of excessive amounts of alcohol. Often said by high school and college students while boasting about their drinking accomplishments.
Bro, I got so incredibly shmoosted last night, I'm never drinking again.
I'd probably do Rosie O'Donnell if I got shmoosted enough.
I feel depressed and withdrawn unless I'm shmoosted.
