What does it mean if all girls and women blush dark red with only one guy who is nerdy watches cartoons reads comic books and plays video games

it means they like "him" or they think he is funny also maybe they are silently laughing at something funny"he" did like a open fly also some girls like guys like that trust me im one of those nerds but my dashing good looks bring all the girls attention to me i think but all in all the girls do like someone is is in the "person's" personlity
