Jacket of All Trades
A guy who thinks he's super cool because he can do a few things, but everyone else thinks he's just average.
'He's a jacket of all trades, but I swear he just thinks he's a rockstar because he can play guitar and cook spaghetti.'
'She's a jacket of all trades, but I know she's just average because she can paint and dance, but not that well.'
'He's a jacket of all trades, but the truth is, he's just average at everything.'
