MOSQUITO (verb): to slyly drink the drink of someone else when they least expect it. There is a high probability of having your drink mosquito'd when someone of the opposite sex who is shorter than you poses for a photograph with you and he/she is really thirsty.
1. Dude, she totally mosquito'd my drink when Aloysius took our photograph with that disposable camera.
2. While she was busy passionately kissing my inner thigh, I took the liberty of mosquitoing her glass of Caramilk liqueur.
