What rude expression would fit most the next situation:
Let's say some people are in a meeting talking about serious work-related stuff. At a point, one of the persons makes a remark to another about not being shaved. Then, the offended person defends itself by saying that the remark is off-topic and should not be discussed in public work-related meeting. Then, a 3rd person would like to intervene by saying something equivalent to 'let me intervene' but in a very rude manner. What exactly would the 3rd person say ? Closest thing I could come up is 'let me stick in' . Is there something worse that can be used in this case ?
