Whats does your name means?

[3 Sheets To The Wind]

... and i'm putting on my pants, and i think ... 'if 3 sheets is drunk, then 4 sheets must be like... drunk...as fuck.'

I'm guessing 5 sheets is worse.. 3 Sheets is the proper phrase though.. so i guess 4 sheets means nothing.. apart from some prick on the pirate ship untied an extra sail than was supposed to lol
