Why would this guy say "She's SOO ugly!"?

ok so I remembered when I was in 6th grade (I am now in 9th) I was sitting behind Richie who is in my grade and his older brother Dean who was in 7th grade and he asked me to go out with him and I didn't want to go out with him. And then Richie said "She's SOOOO UGLY!" and then Dean said "So, she has a great personality"
