In some cases it may be followed by wretching, possible vomitting and acting out in a violent way by the Nawsed party.
'Nawsed'= To personally be annoyed to the point of utter sickness.
'Nawsing'= Personally annoying others... i.e. "Am i Nawsing you?"
'Nawsalicious'= To be proud of Nawsing people right up!
Make up any sick questions like this, and "if you had to, who would you rather sleep with Tony blair or George W Bush? Ask anything like this and sit back and watch the reaction. Rock on! You might wanna stand back, just incase fists come a flying... or anything else for that matter.
Also you can poke people in the shoulder or on the head til they cant take anymore, do skank things like lick slugs, jump around like a monkey making monkey noises, and generally acting like a crazy Naws!
