I saw this sentence in the movie 'The Flamingo Kid'. I've tried to look up the meaning of it in the dictionary, but I couldn't find. Please, help me.
This's one line of the dialogue between a father and his son. They're working together on the drainpipe in the kitchen, while sharing jokes with one another. The father is a plumber.
- Father: Who taught you how to do this?
- Son: Some bum.
- Father: I'll give you bum.
