Technical Term for ‘Annoyances’ [closed]

Is there a technical UX term for an asset/object/function etc that may causes an annoyance to the user?

I'm writing up a summary of a test and really don't want to use the word 'annoyances' as it doesn't sound very professional. We're not talking about a boundary here but something more like a pop-up at an inconvenient time or a section of copy that wobbles to draw your attention.

I was thinking something a long the lines of 'potential barriers to conversion' as the main KPI is conversion in my test.
