When during a serious conversation somebody does or says something (mostly unintentionally) that makes everybody laugh, like tripping/falling in a funny way or making a Freudian slip.
I just talked to my friends and there was a LOL in the conversation when I asked them about the name of a person we just met that day and one of them accidentally said the name of his pet because it sounds similar.
