Harem

A harem is a group of individuals that are married to one person of the opposite sex, often serving as concubines to their marital partner. This is most common in Middle Eastern cultures where polygyny (the one-man-with-many-wives form of polygamy) is practiced, and usually with people of royal families. The term can also be loosely applied to a group of individuals who are in love with, but are not yet married to, a single person of the opposite sex that they are attracted to.

Mainstream Smurfs Media
In the loosest sense of the term, Smurfette in all forms of mainstream Smurfs media has a harem of male Smurf suitors who are all competing against each other to be the one that Smurfette would choose to marry above all others. However, in "Romeo And Smurfette", where Smurfette was confronted with the question of which Smurf she was going to marry, she turned all her fellow Smurfs down for two reasons: she was at the time too young to think about marriage, and that she couldn't decide which Smurf she loved more than any other because she loved them all equally.
