LOL... "glocking" = I pack more heat than an over door.
Bodybuilding is a sport which tends to attract people who wish to improve themselves. Often, people who end up being pros are those who started as short and skinny, not bright, small member, family issue, really anything, and responded well to training and other things. So even though they may be 100 pounds bigger, they still retain that same insecurity. Not all guys, but some. While this new muscle lets them dominate any room they enter in real life, on message board we're all the same 65x65 pixel monster. So, they might get flamed and it takes them back to how they felt as an insecure youth.
It's not all guys, but you def see it more in Bbing than you do in sports like football or basketball. Just something to know, why they take this board stuff so seriously.
