English slang

[Magnum]

I sometimes come across post that you guys and girls post with slang words in it. Being a Canuck I'm not familiar will these terms. What I would like is a little translation of these terms into words I would understand. Help me learn. here is an example:
Tosser = someone who masterbates
Here is some I don't know:
bollocks =
tbh =
squify =
minger =
bodleytunes =
and anymore you can think of. I may have spelled some of them wrong.
