look up any word, like cunt:
 
1.
the thing people do when they should blow their nose, but don't. bigger than a sniffle, so big that one must swallow their snot afterwards. sounds like a cross between loud snoring, choking, and coughing.

an appalling behavior that may accompany getting over a cold.

the act of swallowing a loogie.
"That man's snarfblasts make me want to vomit."
