butter my tulip

when a woman or man have freshly groomed their pubic area and left themselves a small patch or "garden of tulips" of pubic hair to be watered - or urinated on by one's partner. Squirting is also applicable in this situation.

Rebecca's boyfriend just got a Brazilian wax, and he asked Rebecca, "Baby, would you butter my tulips?" In which she replied, "Baby, I've been waiting all day for you to ask me." Rebecca buttered his tulips. Oh yeah.
