A 'crawlleague' is a co-worker or colleague whose lack of self-respect and character forces them to spend much of their working life, and their sad, sad social life on their knees.
Employee #1: Wow, that guy seems to be a rising star in your firm. Every time I visit your office he's hanging on your bosses' every word and staring at him with those big doe eyes.
Employee #2: Yeah, my 'crawlleague' is a real tool alright.
A person who is not quite a friend yet but more than an acquaintance. You take part in light-hearted chat and would most probably only talk to them if you were with a group of people; the same goes for hanging out with them. You also might say Hi to them when meeting in the street, but you wouldn't stop and chat.
Gary: Hmmm... I'm not sure if I can ask him yet, we're really only social-colleagues at the moment. Ask Kyle though, he was at friend level last time I checked.
A workplace cohort who has taken it upon herself to take on the role of a nightmare sister, finding ways to endlessly embarrass, harass, prank and annoy you to the point of near-insanity.
When I wake up some mornings I find myself breaking out in a cold sweat just imagining the weird and unexpected things my nightmare sister colleague might do to me that day.
Fred: So what are you doing this weekend?
Jane: ah, you know just meeting up with my friends and doing other cool stuff with my friends.. so ya I will see you on Monday.. at work.
