玩儿 is the colloquial, erhua (儿化) form of 玩 (wán), used frequently in northern Mandarin speech. It carries a casual, playful tone and covers a range of meanings from 'to play' and 'to have fun' to 'to toy with' or 'to treat lightly'. In extended use it can mean 'to resort to' (e.g., 玩儿手段 'play tricks') or 'to trifle with' (e.g., 别玩儿我 'don't mess with me'). The erhua suffix is not written in standard pinyin as a separate syllable; it is pronounced as a single retroflexed syllable (wánr).
