friend crossover

Friend crossover is when one friend, introduces another friend to one of her other friends. Then, the two introduced friends, become friends = friend crossover. It can cause extreme angst with the friend who made the introduction, because now they are left at home while her former friends have crossed-over and excluded her from fancy parties and are now new besties!

Emily: I wish I never introduced Gretta to Mikayla. Now they are going to Zach's party together, and didn't even bother to invite me.
Cici: You should have known better - friend crossover never works out! Shoulda' never introduced!

Wedding Crashers 

Wedding Crashers is a hilarious 2005 movie starring Vince Vaughn and Owen Wilson as two guys who go around crashing weddings to sleep with girls. It was definitely the funniest movie of 2005.

John Beckwith: Claire's mom just made me grab her hooters.
Jeremy Grey: Well snap out of it! What, a hot older women made you feel her cans? Stop crying like a little girl.
John Beckwith: I wasn't crying like a little girl.
Jeremy Grey: Why don't you try getting jacked off under the table in front of the whole damn family and have some real problems, jackass. Hey, what were they like anyway? They looked pretty good, are they real? Are they built for speed or comfort? What'd you do with them? Motorboat? You play the motorboat?
makes sputtering motorboat noise
Jeremy Grey: You motorboatin son of a bitch! You old sailor you! Where is she? She still in the house?
John Beckwith: What's wrong with you?
Jeremy Grey: What do you mean "what's wrong with me?" What's wrong with you?
John Beckwith: No, what's wrong with you?
Jeremy Grey: No, what's wrong with you? You're projecting!
John Beckwith: Drop it.
Jeremy Grey: You drop it! You stop projecting on me! Why don't you go enjoy yourself while I go ice my balls and spit up blood.
John Beckwith: Drop it!
starts walking away
Jeremy Grey: Team player!

Wedding Crasher 

A wedding crasher is someone who attends a wedding uninvited. Unlike the 2005 film which takes its name from the term, the objective of a crasher may not be to “hook-up” and have sex with guests that were invited but to enjoy free food, cheap or free alcohol, or the party atmosphere. Wedding crashers usually don’t crash the actual wedding ceremony (bride and groom on the altar with a priest) because of the lack of social significance to them and to achieve the previously stated objectives of entertainment, so they’re usually found at the wedding dance, reception, and/or dinner.

The nature of wedding crashers means they may cause trouble at weddings. Since they usually don’t know the people getting married (or other people attending) there is no significance, concern, or respect for the wedding attendees. For example, a crasher may get belligerently drunk and cause a ruckus at a wedding with no remorse since the people there mean nothing to him or her. Wedding crashers are difficult to keep out since receptions and dances tend to be large and most don’t require an actual paper invitation for proof. A small wedding where only family members are invited maybe a situation where a crasher would be easily spotted.

In rural areas or smaller towns where an “everyone knows everyone” environment is prevalent because of small population, inadvertent wedding crashing may occur when people not invited to the wedding ceremony attend the reception or dance after because they have some sort of social tie with people at the wedding. An example would be the person knows the bride and groom, who due to the fact maybe a friend of them would have their presence permitted at the wedding despite being uninvited.

Wedding crashing may also occur with people who know people at the wedding but are not invited because of disputes with guests or even the bride and groom. An angry ex-boyfriend may crash a wedding as a form of vengeance, for example.

"Those two guys over there in the corner have done nothing but drank most of the wine at this wedding. They are rude to the guests, look at them grope every girl here! They are definitely Wedding Crashers.”
