A sexual encounter INCLUDING yourself and two others, not four total people as the moron first thought.
That kid thinks that if you take 1. himself, 2. The person he's talking to, 3. his girlfriend, and 4. that person's sister, and add it up, that makes three...nope... a threesome takes only three people, four and more makes an orgy, you huge dumbass.
