X post decides Y

X post decides Y is a common type of topic found on CE. 'X' is the ordinal form of any positive integer (e.g., "1st", "2nd", "500th"), and 'Y' is the type of thing or action that the X post will decide (e.g., "my sig", "what I eat for lunch", "whether I bleach my ass tonight"). In other words, the topic creator must follow whatever the post of the designated number decides.

The following points are implied in this type of topic, unless stated otherwise:
 * 1) The TC's post counts as part of the number of posts (meaning that the 1st post would be the original post).
 * 2) Multiple posts by a user all count as well. This means that the use of alts is also allowed.

Occasionally the TC will fail to deliver, particularly if the winning suggestion is overly embarrassing, dangerous, moddable, or impossible. Also, if the winning post is deemed stupid by CE, then TC may specify a new post number.

Strategies and tips

 * Constantly refreshing the page is key to accurately timing posts.
 * GameFOX is helpful because it is able to number messages.
 * To reach the specified number faster, you can just make multiple filler posts, including with alt accounts. However, this may be considered spamming and thus be modded.
 * If a good suggestion is posted early on, it may be reposted by other users via the bandwagon effect.

Examples
TC: 4th post decides my Facebook status. GO!!! User1: filler User2: Can we pretend that airplanes in the night sky are like shooting stars? User3: my mom is so sexy, I just want to rip off her blouse TC: dammit User3: Owned.

TC: 2nd poster gets to pick my sig for a week! User1: i like men TC: lame, 20th post is the new post.
