Goshin heck is a word that means ugghhh that’s so annoying !!! This can be used in similar context to what the heck, oh my days(annoyed version) . This word is very snazzy and only elite people use it.
Margret:”I just broke your phone.”
You:” goshin heck Margret that’s so stupid of you!!”
Goshing is when your mate falls in love with a girl 2 days before he meets her. He falls for her more and more even though she is sleeping with half the town behind his back. He is also under the thumb of the village bike!
'Lythgoe, stop goshing ya gimpdon't you know she is shagging everyone behind your back? Nobhead!'
