Profile Sniper

A profile sniper is someone who often has a weak argument, and on the losing side of an online argument, who resorts to viewing the profile of the user they're arguing with to find things to make fun of them for in an attempt to gain leverage in an argument by irritating the other user.

"So, you have to snipe my profile to find something to use for a counterpoint. Go get some valid points to back your argument instead of being a neckbeard profile sniper."
