Why does Plies always use Lil Mama when he's talking about Buckeey in his songs?

When he saw her on "The Flavor of Love 2", he said that she was short but also with a nice size booty. He also thinks that she's freaky in the bed when he calls her Lil Mama and he wants everyone to know that he's talking about her in his songs. Have you noticed that he uses Lil'Mama in the songs that he's talking about her? Have you also noticed that he always talk about her booty?
