Mohicani refers to the Mohicans, an Indigenous people of North America. It's an interesting and somewhat rare word to find in an Italian pop song, making it stand out.
In the context of the song, the lyrics state, "Siamo gli ultimi come i mohicani / Ad amarci così tanto io e te" (We are the last like the Mohicans / To love each other so much, you and I). This metaphor suggests a deep, enduring, and perhaps rare love, likening the couple to the last of a kind, much like the historical perception of the Mohicans.
"Mohicani" is a summer dance track about giving in to a night out and to a new romance at the same time. The music starts, the singer loads up on energy, and by the end of the night he feels like he's dancing his best moves on the floor.
The chorus turns the crowd into a small united nations of dancers: Cuban, Brazilian, Argentinian, Colombian, South American, Jamaican. The music is the one language everyone in the club already speaks, and it's enough to say "I love you" without needing more words.
The bridge takes the couple away from the club to a daydream of a deserted island with no wifi, just the two of them by the sea. Later, the "mohicani" of the title compares the couple to the last of a kind: two people holding on to each other and to a feeling that won't quit, "the last ones standing, like the Mohicans."
