Thry use it to mean this? Urban dictionary vinny someone with a really huge dick "OMG dude, that guy looks like hes...VINNY"
Thank God for that. Apart from it being a very weird thing to tell your mum about it didn't seem to make ANY sense at all as a word
here in Penistone if someone is 'VINNY' they are showing off about their wealth or status (even thought they may not be wealthy)
