i have this classmate, he speaks spanish and i want to say something mean to him cuz he dont pay attention to me so i want to get his attention

i mean i like him and my friend said that sometimes guys like to hear bad things so i wanted to know what kind of mean words i can say in espanol.

my spanish teacher only teaches us nice stuff, but i want to learn some bad things too.

then i met this classmate who is also spanish and he told me how to say this.

1. estas feo [you are ugly]
2. no me gusta tu ropa [i dont like your clothes]
3. tiene el pelo mal [you have a bad haircut]
5. no me gustas [i dont like you]
