An extremely sensitive man who looks for personal attacks in everything you do and say to compensate for his insecurity. Always starting fights.
Simultaneously occupying the other end of the emotional spectrum, the sensie goes above and beyond to try to impress the woman of his fancy, with many flowery words and phone calls and presents.
The sensie is known to make empty threats to piss you off and then love you the next day.
Bob: You never returned my hundreds of phone calls last night.
Mary: Sorry, I was out with my friends.
Bob: You should have made time for me. You don't love me anymore, after all I've done for you! I'm never talking to you again.
Mary: You're such a sensie, grow up and get a thicker skin.
