The bride's last hurrah!!!

So a friend of mine of mine asked me if the bride's last hurrah was a real thing and if I plan to do it, confused I looked at him like wth is that? He then proceeded to tell me he was approached by a bachlorette party at a bar bc he's been selected as a candidate for the bride's last hurrah. Basically the bride wanted him to be the last person she hooks up with before getting married. He declined but the bride along with her friends spent like 20 min trying to convince him its ok and even bought him drinks. I told him this is absolutely something I'm not planning on and that I don't think it's a real thing. But I had to share with my WW peeps and find out for sure bc I've learned about a lot on hear. Some great some bad and some just plain tacky.
