Going to the dollar store with your boyfriend/girlfriend and buying a few things for each other just for fun to show your time together that day/night.
The best kind of gift is a gift that has nothing to do with anything, and it's completely random. Also, a gift that you two can share with each other as well as others. Like a keychain.
Boy: "So what do you want to do at the mall?"
Girl: "hm... let's go to the dollar store and buy random stuff for each other!"
Boy: "Okay, have some dollar store fun."
Girl: "okay go!"
