Ok so here is your next play. Join in on his next poker match. Make it a high stakes game and get it down to just the two of you. Tell him you overheard his conversation. Screw up his game play ability and frustrate him. Use his tell to profit.

that sucks! i can't imagine what your mom would think if she overheard that too. FYL op.

and what would he do OP ??...

How could you post this without telling us what he was saying?

Another dad of the year award has been announced! But unfortunately it looks like your dad is not a candidate.

Cut the old bastard a break. He has to get off on something these days.

as long as he don't know you are around take a gun and end his ******* life , you will feel better after that.

I bet he already did. haha

Well, I think this would just be a huge compliment for your girlfriend, and by association, for you. At least he wasn't insulting her...

What's wrong with some parents I swear
