Sustache 

A swath of facial hair grown to ward off enemies and, consequently, any potential mates;

When a mustache is unavoidably suspicious & disconcerting.

"Is it just me or was that UPS guy giving off some kill-you-in-blue-lipstick vibes?"
"Don't overthink it -- he's just sporting a major sustache."

----------------------------------------------------------------------------

"I almost had her number," Stuart thought to himself.

He didn't realize his sustache was ensuring his worst fear of dying alone.
