Someone who is incapable of handling large amounts of Caffeine.

The type of person who will brag about drinking a whole Red Bull.
You go to Starbucks with your friend(who is a caffeine pussy), and they order a Venti mocca frapuccino, and 5 minutes later they say "omg, I think I'm going to have a heart attack".
