A superlative of Slapin (similar to dope, awesome, delicious) that is used for something that is spectacularly awesome, sometimes food. But it's more than just slappin, you'd need two hands (like a Moose's antlers) to seriously slap for something that great (often used about food)--or lay a virtual slapin on someone who disputed it's amazingness. Also used in a virtual sense about online trolls in live chats.
"Those tacos from the mart next to the gas station are Moose slappin!"
or
"If you type one more stupid thing into this chat, you're in for a Moose slappin!"
