A useful analogy for describing a complete refusal to partake in an activity.
Tate: Hey, hon, that guy that refuses to speak to you, you need to take your relationship to the next level.

You need to hang around his work place and home and once he sees how commited you are to him, he'll change his mind.
Tammy: Right, Tate, hun. I'd rather shave my eyeballs.
