Ballroom Blitz/Playing With

Basic Trope: The villain attacks during a party.
 * Straight: Bob is attacked by Alice at his birthday party.
 * Exaggerated: While everyone's celebrating Bob's party, Alice's forces begin a full scale invasion of the city.
 * Downplayed: A fight breaks out at Bob's party when he has an argument with Alice.
 * Justified: The party was the perfect time to attack while everyone was distracted.
 * Inverted: Bob prevents Alice from attacking him by going to a public place (namely a large party).
 * Subverted: Alice wasn't attacking; she was in on a surprise everyone set up for Bob.
 * Double Subverted: ...which Alice exploited to sneak in her minions.
 * Parodied: Alice is initially opposed by a bouncer, who tries to turn her away for lacking an invitation.
 * Deconstructed: Bob is too afraid to celebrate his birthday in case Alice attacks while all his friends and family are in one convenient place.
 * Reconstructed: Being brave enough to defy Alice by holding it becomes the defining moment of his struggle against her.
 * Zig Zagged: Alice turns up to intimidate Bob, but it isn't immediatly clear if it's going to turn into a brawl or she'll leave after making her point.
 * Averted: Bob doesn't attend any parties which are at risk of being attacked.
 * Enforced: The writers want an excuse to dress everyone up, but the executives still demand a battle of some sort occur.
 * Lampshaded: "I sure hope nobody attacks while we're celebrating."
 * Defied: Bob holds his party in a secure location and has the Hero Secret Service keep it that way.
 * Discussed: "When are we attacking, Alice?" "As soon as the party begins."
 * Conversed: "A party...you know they'll end up fighting while dressed up."
 * Exploited: Bob holds a party in order to use himself as bait to lure Alice out into the open.
 * Played for Laughs: The attack is just one of several disasters that aflict the party.
 * Played for Drama: The attack on his party serves as a reminder of how hard it is for Bob to have a normal life.

This playing with entry's getting a bit tense, maybe you should get back to Ballroom Blitz before- *CRASH* ...too late.
