This is Bob. 

A failed attack against google+ on youtube around 2008. When youtube required you to get a google+ account to comment on youtube, some people were really pissed. Someone created a stick figure out of unicode and other characters and would post it on videos with a message against google+. The message would also ask people to copy and paste it to spread the word. People started copy and pasting it on every video. Some people started creating machine guns and tanks to go along with it. Next thing you know every single video had a huge line of "This is Bob" comments. Wars started between "This is Bob" comments and anti-"This is Bob" commenters. People would flag each other with spam and the such. Finally, in 2010, the "This is Bob" war slowly died down. Some youtubers actually filter out "This is Bob" comments on their videos. You know rarely see them. On ROBLOX you can see "This is Bob" comments warning users about scammers.

This is Bob. 

A real loser, a laugh and a half, someone pretending to be a man.

Based upon a Spike TV advertisement for some stuff that no real man would want in his body.

This is Bob. Bob needs help. He isn't a real man, so he takes some medicine that will be a man for him.

This is Bob's wife. She just fell in love with the medicine and left Bob. See how happy she is.

It's starting all over again... Even 13 years later

Context: In 2008 people were angry because youtube required you to get a google+ account to comment on youtube and they started spamming this on comments.

Someone will post this on a youtube video. ANY video
