The most desired action of endearment. One is to receive this only after they have become exclusive in their relationship. When men receive this act of love they often moan, lick their lips, and beg for more. A woman performs this act of endearment by applying butter to a freshly toasted bagel and then delivering it to her significant other.
The smell of my wife's buttered bagel caused me to wake up before my alarm. That day was the best day of my life, I didn't even have to whisper in her ear... butter my bagel.
