Daddishly

'I don't believe I've met this young man,' he said, daddishly.

You can usually tell an undercover cop by their woefully inadequate attempts to do party behaviour', i.e. standing in the corner with a Corona bopping daddishly to the Wu-Tang Clan, and randomly sticking both hands in the air and shouting, 'Woo, yeah, great pardeee!'

You scanned the party daddishly, as if everyone in the room bore some responsibility.
