One of your "questionnable" friends who, when you try to set up your other friend with some chicks, comes by and steals the attention from said friend. thus making him a communist,thunder-stealing, jerkface!; Also makes you feel like a jerk because your well thought out plan to hook up a friend goes horribly wrong.
"Hey mauro, go talk to those chicks!"
"nah, jesse will steal my thunder and i'll have to go home and cry..."
"yeah, you're right.screw that thunder stealer"
