1.
Pooping on your hand and slapping someone in the face.
2.
Boning a person in the butthole, and then
smacking them in the face with your boner.
"I totally
crappity smacked the Christ out of
Lindsay Lohan!"
"Some bear just came out of nowhere, raped Gabe, and then, to
top it all off, he crappity smacked him. To death."
