An act or being so unbearably cute that you just want to squeeze the individual acting in a cutsey patootsey manner.
When Jess laughs at her own jokes, bikes across Biarritz after drinking a bottle of wine in search of tequila, or gets annoyed when Alex tickles her nose with her hair, she is being a cutsey patootsey.
Something a person asks for when standing in a line, to advance in said line without waiting their turn. This is almost always at the inconvenience of the person being asked. Normally asked for by pretentious women or Jersey douche bags.
Hi, I'm really late for something would you mind if I get cutsees in line?
