Glad you are ok .... it is considered "lucky" to touch somebody's boo boo lump. LOL - Maybe not so lucky for the touchee. ( owie, stop it! Ow, stop it!)
But..... nope, that doesn't qualify for being knocked out. Knocked out is out. Sleepy time. Down and out.
Sounds like you did recieve a good whack, though.
