Taking the word 'pussy' and 'gwarn' (go on) then adding them together to make pusswarn a way to say some one is being a pussy the way the go about their everyday life
Eg: 1
'Did you see warren at that party? he just sat with his
ex the whole night'
'Warrens a pusswarn'
Eg:
2
'
Yo I spoke to brad he said he aint coming out tonight he is feeling shit from
work'
'Brad needs to stop being a pusswarn and just come out!'
