Get the Call Bullshit mug.
The act of calling bullshit: When one person says something that another person is not in agreement with, that second person may "call bullshit" on whatever the first person said. By doing this, they are expressing their disagreement with what the person said in a humorous and yet serious way.
Person1: "Of course I don't drink! I'm not 21 yet so that's illegal."

Me:" Umm sorry, but I call bullshit on that. I was with you last night at that frat party and you were far from the perfect little sober college student you're pretending to be right now."

Get the bullshit call mug.
An American war game phrase that refers to the common Bullshit encountered on Call of Duty, an American Sensation.

Call of Duty Bullshit can cause the repeated use of curse words such as fuck, bitch, queer, pussy, noob, along with others. It has also been related to holes in walls caused by controllers being thrown. It can also cause the banning of your xbox account for harassing the other players.

All of this can be yours for a low price of $60!
(Not including the ridiculously priced map packs)
"Dude it's just the normal Call of Duty Bullshit."
