When some idiot is making no fucking sense, so you just smile and nod.
"Just smile and nod"
Being fake to someone. Acting like you're cool with someone then going and talking shit behind their back. Similar to crocodile tears but more of a "happy" fake.

Person 2: I ain't your brother. Fuck you and your crocodile smiles.
A little smile you make when you're embarrassed, usually by awkward situations or when you do something "stupid".

The whole squad sporting a soft smile in that snapchat. #softsmiles

The fake smile put on at work when you're pretending to be happy.
The business smiling manager loves it when an employee does the business smile.
