Digging Gravy

Flirting with someone who either doesn't realize they're being flirted with or is totally blowing you off.

"I was flirting with this guy last night, but he wouldn't give me the time of day!" "ooh...you were digging gravy. not cute."

Ladler

Someone who shamelessly flirts with another person, but the person to whom their advances are directed doesn't pick up on it or completely ignores it.

"dude...that guy is a totally digging her gravy and she is NOT having it." "wow...what a ladler."
