Get a grip! (4,3,2,2)
I believe this is a double definition.
'get' is the first definition.
(get can mean to buy or purchase)
'a grip' is the second definition.
(purchase can mean grip)
(Other definitions for purchase that I've seen before include "Firm grip" , "Made" , "that has gone through the barcode reader?" , "Obtain in return for payment" , "secure an advantage" .)
(Other definitions for snap out of it that I've seen before include "What one raiding photo album may take" , "cheer themselves up?" , "quickly recover" , "Make effort to emerge from (bad mood) (colloq.)" , "Shake off your bad mood!" .)
