Meaning: The kind of telemarketer who only makes calls to fill in his/ her quota of calls for the day, without listening to the customer
Usage: I asked the ickyickybank tallymarketer to call me in the evening, but she hasn't got back even though it's been 2 days!
Pronunciation: again, obvious
Root: Tally (as in tick mark) + tele-marketer
Note: I think this is a different take on the usual image of telemarketers of only pestering you with calls. Stems from someone I know who actually wanted a credit card, but never got called back!!!
