HODL: verb, philosophy; to buy and hold your Bitcoin, especially when the value is dropping like a bikini clad vacationer jumping off a cliff. More recently been assigned the acronym meaning "hold on for dear life".

The term originated from this forum post.

If you see someone yelling "Sell! Sell! Sell!" there will be 10 of us lurking about to say "Hodl! Hodl! Hodl!"
