In Scribblenauts, any Object that is specifically meant to inflict damage against an opponent. Some of these Objects are meant specifically for a certain type of enemy (like Bug Spray), while others may be unconventional Weapons (Grappling Hook). Even though something like a Football can be thrown to cause damage, it's not considered a Weapon since that's not it's main purpose.
