Lol
Do people actually do this? For real?
MAN WHAT ARE YOU DOING WTF
I don't think it's good for your self-esteem if you do things like this. Imagine telling your grandkids about the time you met: "Uh yeah I was practicing hitting on girls and I felt so bad about doing it that I had to take the tape back to my room and listen over it and obsess about it and then post the results on an internet forum for public discussion"
Don't even think about this. If you're going out HAVE FUN and girls will notice.
Remember fun?
