A token parting gift given to the visitor of a one-night-stand. While the gift is traditionally a waffle, the gift may range from a Pop Tart and a high-five to a knowing, wordless nod as your partner exits your apartment.
"Where'd you get the Eggo?"
"Bonus Waffle from last night. Hey, do we have any syrup?"
The act of giving food, usually of the breakfast variety, in the morning as a parting gift after a one night stand. Not strictly limited to waffles; may also be poptart, pancake, toast, etc. It signals the end of the conversation and an invitation to leave.
"I had a one night stand with that girl from the club last night. After another round of morning sex she gave me a high five and a bonus waffle!"
