How about, "LETS F*ING GOOOOO YOU DINGBAT", now if that's a comment between friends the addition of the insult might be said in jest and still be impatient/enthusiastic, or does by adding the insult to the end automatically label it as combative?
I realise this wasn't part of the dataset, more making a point that written language without context ( and sometimes even with ) is subject to huge amounts of reader interpretation.
