Turtleneck Sweater
1.A Circumstance where a person accidently leaves his fly unzipped and with wearing the right boxers had his dick poke through exposing it.
2.A Fashionable sweater made popular during the 80's into the 90's.
I was in the restroom at the mall the other day and forgot to zip up my fly when I was finished. I had no idea that I was sporting a turtleneck sweater until about after a group of women started smiling at me and pointing towards my crotch.
