Is it just me that thinks this, do men suffer their own "PMS" every month?

I think men suffer from their own "pms". When I worked at a cigar shop and was surrounded by men, I noticed each month it was like clockwork the owner would have pms moments and they would last 2 days out of the month and then he'd go back to being normal. Also some of the other male employees had their "moments". For 4-5 months, I'd jot down dorky notes about their temperment and when I looked back it was as if they were on a cycle. lol What do you think?
