Someone who’s always begging for more credit on an account even though they can’t pay for what they already have.
Ashton was a credit creep who would call all of his credit cards each month to demand a higher credit line even though he never paid them on time.
“Barkeep, I want to open another tab!”
“Go fuck yourself credit creep. You still owe $900 from last month and until you pay it off you will have to pay cash.”
