A person who, more than likely, has a big fleecy blanket on their bed that depicts one or more wolves howling at the moon.

Actual proof of the blanket is not needed to label someone a Wolf Blanket. This is a first-impression label for people who eminate wolf blanket vibes.

Some clues that a person might be a Wolf Blanket: they collect swords, they tuck their shirts into their cargo pants, they wear jewellery with medieval symbols on it, they are overweight, they speak Elvish.

When you see a Wolf Blanket, you just know.
