faceplam - When you facepalm so hard for something so dumb, like seeing

When you facepalm so hard for something so dumb, like seeing a flying shark or someone being a total moron.

'I saw a flying shark and faceplammed so hard I knocked my chair over.'

'He said the Earth is flat again. I faceplammed and my face turned red.'

'She just told me the same joke again. I faceplammed and my hand went numb.'
