Feldhaus 

A large pile of trash created by a drunk idiot mainly consisting of spilt or intentionally poured out beer.

I awoke to a feldhaus this morning in our living room.

Nasty substance, biohazard, or algae that grows inside of bath toys or water bottles

What’s the green stuff that’s coming out of the rubber duck? Oh nothing, just some felchus.
