Why do girls giggle and laugh at me when I was shirtless?

[2tailfx]

I was shirtless on a warm day and some girls were sitting behind a wall giggling , one of them looked around the corner and made a comment and the girls laughed. I am not fat but I have a small, muscular chest.

Girls giggle at nearly everything. If they're making fun of something or joking, they giggle. If they like what they see, they giggle.

Conclusion: don't worry about it.

could be for any number of positive, neutral, or negative reasons, girls will giggle at every single thing under the sun.

Sometimes girls will laugh because they think you are cut and sexy. An indirect approach seeking your response.

They sound immature.
