If you were wondering what the scoreboard signs welcoming Eaumus Catuli or the t-shirts on some Cubs fans that said Eamus Catuli meant, here is the REAL stroy.
Some Cub fan a few years back that failed latin started a story that it means Go Cubs. You can even see signs on buildings around Wrigley that say Eamus Catuli.
Let me correct them.
1st off it is e amus catuli.
E amus means to go or to walk or to march.
Catuli means young dog or puppy.
So the saying "e amus catuli" literally means to walk the young dog.
I guess it is fitting. The Cubs have been playing like dogs lately and Cubs fans always like to think of them as underdogs since they have not been able to get to or win a world series.
Update:
For those angry Cubs fans who have emailed or posted comments:
