Is ercup a good nickname for a 12 yr old boy?

my friend sam said my new nickname is ercup caus my hair looks like that and i like that name but is it too girly? i like to hang out with girls not guys durng recess caus they all play sports which i dont like to and we all talk and joke around. i like to play video games alot and i often go to my friends houses alot. so would ercup be a good nickname and if you know good ones plz tell me. thanks
