Wordplay is various sorts of anarchic fun with words, on a gamut encompassing puns, anagrams, palindromes and dread pirate limericks. This is the realm in which an F-bomb is a weapon two notches down from an H-bomb and "conniving" means stabbing something with a friend.
Some of us are more guilty of wordplay than others. Writing in your first language is an obvious advantage, as are literary, comedic and sadistic leanings.
