bro-&-switch 

When you've invited a male friend to join you for something and he's unable to go, but says his girlfriend or wife is free & he's already told her & she's really excited & where exactly should she meet you?

I had two tickets to the baseball game. I invited Mork, but he pulled a classic bro-&-switch, so I ended up explaining the meaning of the word "bunt" to Mindy.

pig switch 

A switch fitted to the inside back of our heads (possibly placed there by aliens) which will be operated when a certain amount of alcoholic beverages have been consumed. Once the "pig switch" has been operated, a man's behaviour will become very erratic, generally he will cease drinking with his buddies and go on a mission to get laid with any female that says "yes". As a rule of thumb, these females will be ugly in the extreme.
WARNING: Women can often sense when these switches have been activated (possibly by being in tune with their ovaries), and will often use this time to facilitate an impromptu marrage proposal.

Ben: What happened to you last night Bluey? You were there drinking with us and then all of a sudden you dissapeared.
Bluey: I'd had so much beer that my pig switch was activated. I wandered in next door to the disco and picked up the first chick that would go with me. When I woke up next to her this morning I discovered that she was an absolute 3 Tusker

A prank that occurs when a girl leaves the bedroom after sex (to use the bathroom or for any other reason) you hide in the closet while your friend disguises himself as you by covering his body with bedding. When the girl returns she discovers the friend after crawling in bed and getting comfortable.

Last night we pulled the 'ole switch-a-roo on Karen. She screamed when she saw his face wasn't mine.
