The result of getting a chick to suck your knob after you've poked her up the ass. The fecal remnants still attached to your dong will feel like cookie batter in her mouth, complete with the odd peanut or kernel of corn.
Amy had a sweet tooth, so her boyfriend often rewarded her after anal sex with a surprise cookie-mouth.
Short form for "cunt-gut." Basically it's when a woman's stomach, or gut, starts under her breasts and extents all the way down to her cunt. Where a regular belly would cut back in at the belt-line, the gunt finishes much lower.
Being only 25, Amy developed her gunt at an early age.
