Nattiac Arrest is when someone has too much Natural Ice (Beer) to function. One may not be able to stand or speak. It occurs from too much Natty Ice in the bloodstream. A side effect of Nattiac Arrest is believing that Natty Ice actually tastes good or saying that is tastes smooth.
“Yo bro how low can you go, oh this Natty Ice tastes so smooth.” This is what someone would sound like if they are going through Nattiac Arrest.
