The first poster writes down a name they love (ex: [name_f]Ivy[/name_f] [name_f]Pearl[/name_f]), and the next poster gets creative with the name and changes it up to fit their style (ex: changed to [name_f]Iva[/name_f] [name_u]Ruby[/name_u]).
Then, the next poster says which one of the variations they like the best. (ex: I prefer [name_f]Ivy[/name_f] [name_f]Pearl[/name_f]) You add a name at the end and keep the chain going.
