forced laugh 

an unnatural laugh, one that is used to cover up emotion or when you aren't feeling the funny but have to laugh due to politeness

I managed a forced laugh when they made a stupid joke.

Forced fake laughing is done when a loser doesn't know how to react properly to something because it makes them uncomfortable but they still want to act like they are high energy and extroverted when in reality they are not.
