Someone who habitually bursts into doors unexpected. This can be at an office or at somebody's home or apartment. The intrusion causes negative attention from everybody in the room. It can disrupt conversation, ruin appetite, or cause a major cockblock.
In the tv show Seinfeld, Kramer is Jerry Seinfeld's neighbor who always opens the door to Seinfeld's apartment uninvited.
