Nearly right. It's a beard. Moustache and whiskers. A full beard
But do you expect the international user's on this forum to understand old English navy terms
What you've written is 'Grow some balls'
But you can't be told ever, can you
And it's not what the royal navy call a full beard it what the navy rules say a full beard is
I expect people you actually read and understand. I know its difficult for you but please try. I will make it easy for you
"Grow a set" an insult
"Grow a FULL set" full beard and moustache.
So it seems your insult backfired because of ignorance.
