Cold wave 

The feeling when someone you like/ are attracted to do does something nice/ says something sweet to you, which produces a tingy feeling in your body (sometimes goosebumps)

When I hugged my crush, I got a cold wave

cold wave of heat

A temporary feeling of love that makes you go into a blissful state of a straight gullibleness for the person the flatters you.

when I see you, a cold wave of heat washes over me everytime I stare into your eyes.

when you text me you make me feel a very cold wave of heat.

Coldwave 

Funnily enough, the name of two different genres:

French coldwave: a sort of proto-goth rock sound that developed in the late 70s.

American coldwave: guitar-driven electro/industrial music that enjoyed brief popularity in the early 90s.

To fans of both genres (author included), watching people get pissy about the difference can be very entertaining indeed.

French goth: mon amis, i hear you like ze coldwave?
US rivet head: yeah, bro, totally! just bought the new 16volt album, shit was SO cash...
French goth: qu'est-ce que c'est, 16volt? do you like trisomie 21?
US rivet head: who's that? have they remixed any Chemlab tracks?
