The large open space on the forehead of a gaper between the helmet (or hat) and goggles while skiing/riding. Also visible days after in the form of a sun burn or wind burn on the forehead.
Gaper: Man, my forehead got fried skiing this weekend!
Local: You need to pull your helmet down and cover your gaper gap.
My wife had a gapey after an hour of pounding my cock up her asshole.
The gynecologist could tell that her patient engages in a lot of anal sex because when the patient bent over on all fours to expose her asshole, the patient had a gapey.
After some severe anal penetration, if the girl's gaped,moist, ass is said to be so irresistable that one can't resist thrusting his/her tongue deep inside her juicy, tasty asshole,to retrieve all the anal juice waiting to be digested once again, then her ass is undoubtedly .... gapelicious.
Mark:John, what's up with your tongue?? It looks all swollen.
John: That bitch!!!! She tricked me!Last night whilst I was sucking all the juices out my girlfriend's gapelicious ass, her asshole tightened up on my tongue, leaving it bruised.
Mark:What can I say? As inviting as a gapelicious ass might seem it cannot be trusted.
