Bump to Top. BTT simply adds a posting to a forum thread to show activity, thereby moving it to the top of the list of threads in that forum.
For instance, if a discussion thread has been inactive for a week, it can get moved down in the list or onto subsequent pages. Any activity in the thread will move it back to the top of the list.

Posters may just want to do that and will post a BTT.

BTT is the shortened version of The Bad Touch Trio

The Bad Touch Trio is a trio from the anime and manga Hetalia: Axis Powers. The BTT consists of France, Spain and Prussia. Sometimes referred to as Francis, Antonio and Gilbert if your using their human names. The 'Bad Touch' is talking about their flirty and slightly perverted attitudes.

Some people say make jokes that they are the 'Wierd Laugh Trio'.
Germany: Prussia! Stop having Bad Touch Trio meetings!
Prussia: Never! Kesesese! The BTT will live forever!
