A ‘coyshy’ is when a guy tells a girl that he isn’t ready for a
relationship but keeps the girl around for months on end just because he is
horny. A person can also be said to pull a coyshy if they do not have the balls to ask the girl out as a
girlfriend.
“Fuck me, can you believe that Liam’s pulled a coyshy with
that girl for 5 months?! The poor girl is
desperate for a boyfriend but he won’t
budge”
