Following on from a conversation with Katex on facebook (Katex didn't know what belm was.) This is a fab photo of a woman doing belm.
Who else remembers belm?
We belmed at someone when we thought they were lying.....e.g I won the lottery this weekend....BELM!!!
I'd forgotten all about it until someone mentioned it yesterday and since then I've been belming at everyone!
I haven't belmed so much on years! It's fab.....forget sticking fingers up, get belming!
