Which is crazy because I've only used it once or twice but each time I've noticed many people use tongue in cheek descriptions like "for drugs" or "strippers" when they are just splitting a bar tab.
You will get called for this - I had a friends whose summer job at venmo was to call people and ask them to change the description from ‘sex’ or ‘drugs’ to something more innocuous - or to please stop buying drugs through Venmo.
