It's just English words bastardised into hangul.
giputu=gift
isu=is
yo=an attempt at 'how'?? maybe 하우 was too long for them?
then giputisyo is how it sounds when you stick that all together and say it quickly i guess?
I struggle to see how giptisyo becomes giftishow too, but this is their app, with giftishow as the english, and it's also the url of their site

Or maybe it's meant to be Gifti Show or something??? But then what the hell is Gifti
