Email i received as an answer to the question from a big shadchan that claims to deal with the heimishe crowd:
chasidish = you have a rebbi either alive or not and follow their minhagim and Mesorah.
Yeshivish = you have a rosh yeshiva either alive or not and follow their minhagim and Mesorah.
Heimish = i can do what ever i want i don’t need to follow chasidims minhagim because we are only “heimish” and we are not either yeshivish.
there is a phenomenal of yeshivash heimish or modern heimsh that would mean chasidic background and some chasidush minhagim.
