What does the german word "schmeiss"mean?

Answer 1

It would be nice to have the word in a sentence but for now I can only guess:
The only German word that comes to my mind is schmeissen (schmeißen) which means to throw smth, also to drop something (e.g. drop school - die Schule schmeißen)

schmeiss would than be the imperative

If the word is really Schweiss (Schweiß) than it is sweat (as a noun)

As said before: It would be fine to have it in context to give you a better answer
