Why does my girlfriend call me "tasty" and "delicious" or similar as a NAME all the time recently?

... i'm not a desert! Why has she taken to calling me these things recently... it just seems more than a little odd when just out of the blue she calls me these things, it's not that she describes me as them, she actually CALLs me them...

... she started since she left to stay in another country for a month and she's been doing it the last few weeks
