Would a friend who spoke vulgarity for 2-3 hours irritate you?

we have a friend who is great when sober but after a few drinks talks to his wife and others in general in a very vulgar manner. this has happened many times but this past weekend it was off the charts. he thought it was all funny but no one else was laughing. i think if he wants to talk smut with the guys .. fine. and if that is acceptable with his wife in private fine. however my husband and i wanted to leave after hearing this for over 2 hours and he kept interrupting people with his funny haha comments. we could tell his wife was ashamed as well. any suggestions on how to deal with this ?
