When I deleted all the premade Sims for my Empty World save (re-filling the game with my own Sims and houses mostly), all the clubs were deleted, but the game developed new ones including names. My favorite is the fishing club called One For The Halibut. :D
I use clubs mainly to gather Sim easily for social events. I have my Happy Fun Club for my child Sim, though that one will soon be disbanded because my Sim and her friends in the club will be aging up to Teen, at which point I'll start a new club so they can go out bowling, nightclubbing and karaoke singing. Often as family members age and move out I'll make a club for the YA+ siblings so they can gather to go out to dinner or for holiday dinners at home.(Can get tricky when you've got a large family so I usually limit it to just the siblings, no spouses/partners.)
