Guy's Behavior

Is it weird that my boyfriend did this in front his friend?

boyfriend and I been together for three years, great guy. Went to a wedding met one of his best friends who is funny as hell and always makes jokes. Anyways while drunk, he told me a joke about how my boyfriend when they were younger told him he can make his balls clap when he runs fast and showed him my thrusting hard in his shorts. His friend was laughing and I thought it was funny but kinda weird I know guys do dumb shit but is that weird?
