Where you feel shit the next day as a result of tiring yourself out the previous day. The equivalent of a normal hangover but without the alcohol.
Kevin had one bitch of a tiredness hangover today after fucking that new girl of his for 10 hours straight yesterday. He's gonna need a lot of caffeine and sugar to pick him up.

The feeling you get after a one night stand with someone you really like. Could also be called a crash after the high sex causes.

Jim: Hey, man, you look terrible!
Jack: Nah, it's just a hockey hangover. I stayed up to watch the Stanley Cup final game last night and then I stayed to see who won the MVP of the playoffs and then they interviewed the captain of the team... and his wife... and kids and then they went back to the dressing room where they were drinking champagne from the Stanley Cup...

After a satisfying night of sex with a very hard boner, you wake up the next morning to find your normally limp dick to be thick and bouncy, easily aroused and extremely playful. This lingering effect is often surprising to men who find themselves endlessly baiting their morning away. A good Viagara Hangover should not be wasted!
Mike took 50mg of Viagara last night before having sex with a random stranger. He got off twice, but the next morning brought a Viagara Hangover that could not be contained. Instead of going to the gym, Mike took over 100 pictures of his extra swollen member.
