What does :/ mean in chat? Does it differ depending on context or not?

[Sam]

:/ Is used in serious or humorous ways. It can be used to portray that the person it unsure, an awkward situation or a 'weird' situation. For example, I could say,'My dog just ate my dinner :/' or 'I don't know if I should get a tattoo or not :/.'

[creezy]

:/ means the : are the eyes and / is the mouth's placing.

Slack jaw, not knowing whether retarded or serious a sort of dumbfounded expression.
