A grimsey is someone who is just Awesome. They are swag and are pretty much a lad in general. No one can be a 'Grimsey'. Like in the movie Grimsby. Grimsby is a tier two Grimsey with A grimsey being tier one. If someone is a Grimsey then they just radiate Swag
'Wow he is such a Grimsey' 'Yeah I know he always knows how to do everything'
