The Leper

Whilst having sex with a girl keep a sausage (raw or cooked) in your hand. After a few minutes remove your penis from her as you shove the sausage inside. Tuck your penis between your legs and scream. As she turns around she will still feel something inside her but it will look like your penis is missing.
This is called The Leper.

Bonus points for adding ketchup or fake blood for extra realism.

'I'm going to have sex tonight!'
'Make sure you do The Leper, here, take this sausage.'
'You're a great friend.'

The Leeroy Jenkins 

When you and your partner discuss at long the intentions of your sexual persuits right before you make love. Then at the last second the male abandons all this and screams, "Leeroy Jenkins!" and just penetrates and goes to town.

We spent an hour cuddling and "planning" last night before me and my wife were going to do it. Then right when she was ready to start pulled The Leeroy Jenkins, screwed the plan and went right in!

Chase the Leperchaun

To follow up an Irish beer with illegal activity.

Seamus: Did you hear what happened to Joe.
Mick: Well that's just what happens when you chase the leperchaun.
