Nickname for any valuable "resource" (money, expensive food/gifts, gasoline to give her rides where she wants to go, hot and/or arduous mechanical/carpentry work, patient endurance of boring/cutesy "
girl stuff", etc.) that a naive "
dairy farmer" (mushy-hearted guy with
raging hormones) "feeds" to his "cow" (an attractive girl whom he hopes to win over) in an effort to please/satisfy her so that hopefully she'll feel enough favorably disposed towards him to "allow him to milk her" (spread her legs for him) sometime later. May or may not be successful, depending on how “loose” the chick in question is, or how much she respects the guy’s feelings or truly appreciates/values his caring efforts to help her out.
Stud #1: Yo! Why the long face, dude? I take it you didn't "get to 4th base" with Tiffany?
Stud #2: Nope! And I fed her a whole
BALE of hay, too --- worked my butt off for three hours straight in the scorchin' sun to get her car road-ready again, and
burned up three of my brand-new
DeWalt cut-off blades in the process --- but then afterwards she claimed to have suddenly "got religion" and wouldn't "give me any milk", even though she'd promised she would if I'd fix her car.
