Cry wolf about something like thats bad, but the result is harmless but the result of a laugh wolf is comically deceptive
just a laugh wolf tactic
Probably best done with anyone you know well and get along with
Or people you really dont like to make them smell your fart one day for example
when you cry wolf about a fart for example and they find out you've been lying and then when you really do fart and admit it... and they find out about it because they dont know if your lying or not...
Laugh wolf
result of a cry wolf, being a comical one
