Secret messages from youtube?

so this morning i signed into my youtube account. as soon i had been directed to my channel, i see this pink bar across my web page, it said 'I shenanigans'. it was very odd as i couldnt figure out what that meant. but i did a youtube search and saw other users had the same problem. supposedly it's some kind of glitch that's been happening for awhile, so idk.

UPDATE:
it happened to me again the other day and i took a screen shot >.>
