Fun rules for a trip with the boys

In a couple days im going on holiday with some friends and we all have to make up a rule to follow with an alcohol related punishment. So far everyone has a rule except me and i can’t for the life of me think of anything.

So far we have

Last one to wake up in the morning takes a shot

Everyone must talk to at least one girl during the trip or give a round when we’re back home (those who have a girlfriend are exempt and can instead tell one person each day to do a shot with them)

first one to go fall asleep has to chug a drink the next day

the first sip of every drink must be drank by someone else of your choice

first one to throw up gives a round the next day

skipping a song in the playlist costs 3 sips

person with the least amount of steps at the end of the day has to chug

If anyone is more creative than me and can think of a rule we could implement it would help out a ton.
