Noun. To yank someone's collar or, preferably tie, violently back and forth while yelling "are you a Japanese dog?". This will no doubt cause them to snarl angrily, much like a Japanese dog would if you jerked their collar back and forth. Giving someone a Japanese dog is frequently considered a merse.
Marshall totally gave Christian a Japanese dog before his Spanish presentation. Christian had to stand in front of the whole class with his tie fucked up!

When you're having sex with a girl in reverse cow girl position and then she gets up and shits on your dick. Then you cum on your own dick and she sucks it all off.
