Not so much phraseology but poor RT eg:
1. The old chestnut of giving someone a frequency change and they go without acknowledging
2. You ask them a question and no response so you ask them again and you realise that all the time they were working on a response - why don't they say 'standby' so you know they've heard you the first time?
3. Supposedly cool phraseology like "PD to 350" = "Pilot's discretion to FL350" etc
No guesses for the nationality producing the bulk of the above
