Outdated term?!

[tinypenny]

There was an incident at my library the other day.  Tempers are easily set off since it is finals here and two students were yelling obsenities at each other.  I had to notify the campus cops before punches were thrown.  I called and told the officer who answered that we needed them to come to the library as 2 students were about to "come to blows".  The response I got was a shocked and dismayed, "WHAT?!"  I had to pause for a moment...very perplexed, I responded "punches, fighting".  I was told later by someone that the officer probably thought "coming to blows" meant something sexual.  Am I that out of touch with popular lingo that I didn't even think that people wouldn't know what I was talking about?!  After everything was resolved, I thought about what happened and have come to a conclusion, if something similar were to happen again, I am soooo using the term "fisticuffs".
