Firster
Someone who enters a numerical position on a message board or social network post such as first or second but adds no meaningful insight or opinion on the original post. Statistically this will fail and makes the firster look idiotic and annoying rather than just being annoying for wasting space.

This is similar to trolling but lazier and not as creative. It's kind of like Trolling for Idiots.
The topic would go here and then the firster would post as such.

Bojeezy - FIRST!
Bukkake4me- 2nd!
Admin- Well that was informative...and creative..
