to ahoy something, means to knock an object out of the control of ones hands, whilst shouting "ahoy!", sending irritation into the victim's spine.
victim: "here, look what i've made" (victim carries in a shit cocktail that seems to be so impressive to the victim)
predactor: "AHOY!", whilst knocking the drink into the next-door's gerden to the irritation of the victim :
victim: "whats the point in that" in an idiotic, nearly retarded voice.
