The opposite of Firsties. A comment so out of place or terrible that it ends the online conversation taking place on a particular blog
post, forum thread or
Facebook wall
post.
Hey, I know you simply wanted to show your affection by commenting on my wall or blog
post, but you have clearly missed the entire
point and your comment was effectively the stopping
block of what could've been an engaging online conversation with social peers. You just made a Lasties.
