Need to get this off my chest guys

I've only worked at my current company for around 7 months and apparently Halloween is a really big deal to the people who work here. So big that there is a competition for who's team decorated their cubes the best and who is wearing the best costume etc.

It has been the buzz around the office for the past week and I prepared myself for today and all the stupid costumes the waymnz would be wearing ( I work on the marketing team and it's 80% waymnz) and made an even greater effort to ignore them and make sure I take the stairs instead of getting stuck in an elevator with them. Overall it's working fine I'm focusing on my work and ignoring the craziness going on.

My problem today is not with the waymnz but other guys that work here. Today just so happened to land on the day we have our quarterly company wide meeting, afterwards the company provides lunch for all the employees ( 1000+ people ).

I'm walking to get in line for lunch and notice the "person" in front of me in line is a guy wearing a wig and dress pretending to be I don't even want to know what. I don't think I could have stood behind him without saying something so I get out of line and use the restroom. On the way there I see a guy on another team we work with every once and a while wearing a one piece cow costume complete with udders sitting at a table with a group of wamynz who are all wearing the same thing, I gag and have to hold down some vomit.

What is wrong with these men? Do they have no self respect?

I wanted to slap them both to knock some sense into their heads.

That's all. I feel better now.

tldr Ignored waymnz in costumes, annoyed by males wearing a dress and cow costume
