Underwooed 

To fail notably to impress or excite somebody; a feeling that someone gets when it is obvious that the other party has put forth little or no effort to gain your love or affection.

Ericka: During Jud’s absence, both Stephen and Bob contacted Janine. Stephen made reservations for lunch at her favorite restaurant, greeted her with Godiva chocolates, apologized profusely for not calling her, and stated he was an idiot. Bob met her at Panera, and didn’t even offer to cover the cost of her coffee.

Anna: Wow. She must have been totally underwooed
