Steam does this to me. Some games use an Invite button to open a special steam invite menu. This shows all my friends with an invite button next to them. It also insists on dynamically sorting the list based on the person's current status (ex. Starting/stopping a game). So if I hover over the invite button for someone, and someone higher than them in the list moves lower (or vice versa) right before I click, suddenly I'm inviting whoever happened to be adjacent to them in the list. This has only led to an awkward "actually I didn't mean to invite you" conversation once.
