3. They have a caring soul
Sarcastic boyfriends know that they are hard to deal with. But there will often be times when they will go out of their way to show that they care. If you are having a hard day or have done something special, sarcastic boyfriends will pull out all stops and do something special for you too in return. For instance, they will act all nice and proper when out in public. They will be a true gentleman with you when out on a date instead of passing snarky comments at everything. In short, they will do something out of the extraordinary and surprise you.
