sisterpathically

When sisters can communicate with out speaking. Like telepathy but when your sisters.

My sister was deep in thought and I didn’t have to wonder what she was thinking because I communicated with her sisterpathically.

sexternality

A cost or benefit imposed on a third party by a couple having sex.

My roommate and his girlfriend's refusal to dispose of condoms properly presented a pretty serious sexternality to anyone using the sidewalk outside their bedroom window.
