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!
