Well isn't gambling the same as any other addiction in that if you HAVE to gamble or do it even though you can't afford to then it's problematic? A friend here who's husband is a gambler gambles money he doesn't have and gambles away money that he needs to live on.

What you're describing sounds harmless enough. If it's occasional, and it's pure fun, then why not?

Go, have fun, male bond! (that doesn't sound right)

Oh just for your information, it wasn't my birthday. Don't ask. It's a longgggggggggggggg story.
