The cum that gets stuck to your leg after masturbating in the shower. You think you've washed it away, but its always there once you get out of the shower.
"Oww man I got voje on my leg, again!!"
"Dude this voje just wont wash off"
A hardo is a person who tries extremely hard at everything. Most times a hardo will try very hard at things that do not require excessive effort. For example, sports practices, gym class, etc.
Wow did you see Jack at practice today? What a hardo!
