The song "Boo" by Hot Freaks is a love song about a person who is deeply in love with their partner, but their partner seems to have different interests and tastes that others might consider lower or "dumb". However, the person loves their partner despite these differences and wants to convince them to love them back. The chorus repeats the phrase "You know I love you" and asks for their partner to say yes to them. The lyrics also mention the couple's plans for the future, including going out all night and making bodies feel right, and having a son who will grow up like his parents. The phrase "hot lemonade" may refer to a type of alcoholic drink, while the mention of Kesha, Timbaland, and KC and the Sunshine Band suggests that the partner likes pop and dance music. Overall, "Boo" is a simple yet heartfelt declaration of love, despite differences in interests and tastes.
