to be like HEY

... is to take the initiative in an interpersonal relationship which may or may not lead to romantic or purely carnal activity.

Tasha: "Why don't you just go up to Nate and be like HEY?"
Tina: "Because I've done all the work so far, so I want HIM to be like HEY."
Tasha: "You're right. Guys are SUCH pussies."
