If you're a male, while receiving oral sex, just as you're about to ejaculate, you scream, "Gyarados. Use Hyper Beam!" Then you ejaculate on her face. If she starts complaining, say, "Gyarados must recharge".
most feared move in MVC2, especially Air Hyper Viper Beam, is infinite move and can be done 5 times in a row(max meter for Marvel Vs Capcom 2). beam move has priority over all other projectiles including the worthless hadoken's to cyclops optic blast and IceMan's ice beam.
