how would i parse this with string patterns?

i want to make it so anything inside :/ gets put in a table for instance

:ehh/ and then in the table there will be the text ehhh but say i inputed :ehh/:Doge Is Cool/ then it would first input ehh to the first value in the table or TableName[1] and Doge Is Cool would go in TableName[2] all in the same string

.. ive been trying and im stumped
