When a baby is tired and about to go to sleep. Instead of a baby going to bo-bo's the baby goes to bosey.
'she is a bosey-baby' meaning she is tired or asleep
When you make a promise whilst crossing your fingers. Meaning that you don't have to keep your promise.
'I was so annoyed when she cross-promised'
When you are being blunt and honest at the same time
'I admire how blonest she was'
