Have a bunch of your friends hide in a closet with cameras. Seduce a girl and have sex in the room with the closet full of your friends. Right after you orgasm yell, "British Invasion!" and have your buddies come out and take pictures the girl while she still lies there in shock. This act replicates the British Invasion in the 60's in the sense that British bands would constantly be chased by the paparazzi who would take pictures when they least expected it.
Woman 1: How was your date last night?
Woman 2: Everything was going fine, until that asshole called for a British Invasion!
