One who spends 12 or more hours a week masturbating to his or her pornfolio.
Randoguy: "Dude, did you know Billie was a Miscer? He spends all day checking out his pornfolio!
Randoman: "ZOMFG! Keep the Miscer away from MY pornfolio!"
A miscer is a member of the misc section of the bodybuilding.com forums. While most of the bodybuilding.com forums are geared towards the bodybuilding lifestyle, with a few exceptions, the misc section is generally where all the unrelated random topics tend to be posted.
Miscers are predominatley male in the 18-34 age bracket. Although many claim to be avid bodybuilders, a lot do not look it judging by their avatar pictures.
Miscers tend to be a cynical, impatient and fickle lot and do not take kindly to unfunny trolling. Said trolls are often dealt with harshly and negged to oblivion.
Most miscers are looked down upon by other members of the forum because they post almost exclusively in the misc section and many do not even work out. It is also where most of the forums trolls congegrate.
To make it as a miscer your main goal should be providing entertainment to the other misc members. Probably the easiest way would be providing comedy relief or posting something informative or of an 'epic' nature.
