It can also be meant as different nouns like eating some shmeegers or going to the shmeeger.
Also if you are annoyed instead of using a curse word shmeh is the perfect replacement
i got so wasted last night because the bartender kept giving me so many shmeegers.
the last time i was ill, i had to go to the shmeeger, but he gave me some shmeegers, so i got much better.
im so hungry i could eat an entire bowl of shmeegers.
