Schlafsack 

sounds really disgusting; is a good insult (it really just means sleeping bag in German)

Guy1: "I sleep in a schlafsack at night. You should try it; they're real comfortable."

Guy2: "...wtfff??/"

Schlafsläcken 

When you're too lazy to get up to pee in the middle of the night. More generally, when you're too lazy to get get out of bed.

I didn't sleep well because I had severe schlafsläcken and should have gotten up to pee.

Schaafseckel 

"Schaafseckel" is a swiss swearing word, that translates to: "Sheep testicles". It is mainly used in the inner part of switzerland. You can often hear it from farmers or school kids in that region.

You're such a Schaafseckel.
