1. Someone who is clumsy or bumbling in their movement or behavior. He always turns into such a stumblebum after a couple glasses of wine. I've been a stumblebum my whole life. Maybe clumsiness is just genetic.

2. Someone who stutters, stammers, or rambles when they speak. He's a great actor, but he's such a stumblebum when he's being interviewed that it is hard to take him seriously. I have no problem talking to small groups of people, but I turn into a total stumblebum when I'm in front of a big audience.

3. A drunkard. His old man's been a stumblebum for years. It's why he can't hold down a steady job. The thought of becoming a useless stumblebum like my mother was enough to keep me away from alcohol my whole life.

4. Someone who muddles their way through something in an inept, haphazard manner; a blundering, incompetent fool. With a stumblebum like him running the company, it's hard to believe we haven't gone bankrupt yet. She may have been an amazing businesswoman, but she is has been absolute stumblebum as our governor.
