[name_f][/name_f]! I do like [name_f]Maris[/name_f]. It reminds of the ocean, because of the [name_f]Mar[/name_f] in the name. [name_m]Ari[/name_m] is a very cool nickname.
Mimo is indeed very courageous in Portugal, although my sister already calls me [name_f]Mima[/name_f] as nickname so

A friend in primary school used to call me [name_f]Mimosa[/name_f] as a good natured joke
