London: Writers have come up with an easy to use tool guide to help decode the underlying meaning of women's body language and behaviour.

Mal Croft and Matt Windsor with their The Secret Body Language of Girls claim to decipher the visual signifiers of female interaction.

The guide, priced at 6.99 pounds, offers a tongue-in-cheek interpretation of what signals women might be sending, even without their own knowledge, a daily reported.

For example, a woman biting her lip during a conversation could be sign ''Whoopsy daisies'' or ''I shouldn't have said that'' while a girl sticking her hand to her ears pretending it was a phone could point towards the cries of ''call me''.

Also, the lifting of the forefinger to the lips or 'The Shush' sign could mean she wants silence and has lost interest in the conversation.
