A new yet unknown
phenomena. When a person (usually a lolcow) posted
something that was very serious in an extreme manner, the flamming/trolling against these types of people
immediately stops and he or she becomes a wtfbull for the rest of their lives. Unlike lolcows, wtfbulls grows an amount of wtf and lose (similar to how a bull grows its horns). Due to this, the said person can cause you to go insane.
Do not approach them, avoid them at all cost and run for your life because you may get hurt by their "wtf" horns.
