A Royal Flush
First flush: You took a massive dump and you gotta flush before wiping or the toilet will clog up like a pig's ass. Second flush: You wipe and then you flush again because the toilet is now a sad little puddle. Third flush: You flush one more time just to be a nice guy and make sure the next person doesn't get a face full of poop water.
First flush: I had a full-blown food coma dump and had to flush three times just to get out of there.
Second flush: I wiped, then flushed, because I didn’t want my brother to get a surprise poop splash.
Third flush: I flushed again just to be a hero and save the next person from my dump legacy.
