"Beat your butt" here is an expression that means to defeat someone or win in a competition. Usually, the more common way to say this is "kick your butt". Both "beat your butt" and "kick your butt" are nicer ways to say "kick your ass", which is also very common. Ex: He beats your butt in the race. Ex: We are going to kick the other team's butt in the soccer game today!
