Mexican Lane Change 

When you're having vigorous sex with a female and your cock comes out of her vagina and either inserts or pokes her ass hole.

It is typically not well received.

We were doing it from behind when i did a mexican lane change and it was not appreciated. An apology is usually required.

head change

The feeling one experiences when a noticeable form of intoxication is present in ones mind. This change in the head could be from smoking either marijuana or tobacco.

Keep the change

When you impregnate a girl, do not stay around to be a father figure and do not pay for child support.

Dude, I think my condom broke when I was having sex with Molly Last night.
Do you think she's pregnant?
I don't know, but if she is I'm going to let her keep the change.

Venue Change 

Leaving the office and going to a bar with wifi during the work day to drink and work at the same time. Multiple "venue changes" can be made during the same work by switching bars.

Matt worked all day but made multiple venue changes and was fairly unproductive by 5pm.
