Dear diary?

Guess I should have read the OP and not just the title. Although that in itself shows the type of quality posters this sub is known for. 
  
 Actual answer to OPs question: This sub used to do a lot of YOLO plays, especially on pharmaceutical trials. Basically any play that is sure to either lose a lot of money or win a lot of money, back when this sub was comprised of people with actual brokerage accounts. Gambling on SPY fd's has always been popular as well.
