Someone (mostly guys...mostly) who use their substantial stomach to barge into a group they are not part of. Accomplished by leading with the belly into the personal space of others until they move, allowing the belly bully room.
The three of us were having a great chat until Sam barged his way into our group, he's such a damn belly bully. He's like a tugboat with that gut.
