My friend group was always on the nerdier side in high school. One thing I'm really glad we did come senior year was we'd play poker, and the loser, if single, would be have to go and ask a random gal out on a date (with the rest of the group trying-yet-failing to act casual hanging out nearby to make sure it happened lol)
It's liberating to know that, as long as you're not being a creep, you can just talk to someone you think is cute and ask them out. It was especially nice to know back in the high school days lol.
