Football season is over of course, but you can use these for any sport. It’s not like Latin had a real equivalent for “touchdown” anyway.
Sequimini, sequimini, facite ut pilam relinquat!
Pursue them, pursue them, make them relinquish the ball!
Illos repellite, expellite, compellite ad fugiendum!
Repel them, expel them, compel them to retreat!
Utinam vincamus!
Oh, would that we would score!
Volebamus atque volemus pilam trans metas deponi!
We have been wanting and shall continue to want a touchdown!
Those are from Latin For All Occasions, by Henry Beard, a Classics major who went on to co-found National Lampoon. For years people gave me books like that.
Here’s a bonus (under “LATIN AT THE AIRPORT”) that might come in handy as we enter the imperial era:
Recedite, plebes! Gero rem imperialem!
Stand aside, plebeians! I am on imperial business!
