A dick you get while out on a trip, usually surprisingly large in size. You can't take this dick on a daily basis which makes it perfect for a temporary vacation.
I got some vacation dick when I went to Vegas. Oh boy was it big, but what happens in Vegas stays in Vegas am I right?
a very huge penis usually found in male porn-stars and strippers, mostly over 10 inches long and is not very common within the male community that hasn't had surgery
OMG I slept with some dude at the bar last night and he had a vacation dick, IT HURT SO MUCH! ( ͡° ͜ʖ ͡°)
