bags
What does bags mean?
Your holdings of a particular token, coin, or NFT. 'Heavy bags' means you hold a lot. A 'bag holder' is someone stuck with a token that's tanked — left holding the bag while smarter money exited. 'Fat bags' is the opposite, a position that's printed. The word does most of the emotional lifting in any crypto conversation about who owns what.
Origin
From the older finance term 'bagholder' (someone left holding worthless securities), which itself traces back to 1800s con-game slang. Crypto Twitter shortened and softened it into 'bags' as a neutral noun for any holding.
