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!
A bunch of socialist British bands who were already famous in Great Britain who came to America and the second they got here started singin about how disgruntled they was about the American way of life.They disgruntled an entire generation with their drugs and their music and to this day this country is still FUCKED because of it.
British Invasion is when a bunch of commie-socialist faggots come to your country and fuck it up beyond repair for decades with their gayness and their tree-killing hippie bullshit!!!!!
