Not sure if this has been mentioned yet -- been off VLR for a while and searching the forum doesn't show anything.
Tejo's name is also the name of a sport that is very popular in Colombia!
Tejo is a sport that uses a metal or stone puck (called a tejo) that you chuck at a small board full of clay and some small targets made with gunpowder (called mechas). It's an old sport with links to the aboriginal people of the region. Points are scored based on where the tejo lands in the clay, with extra points depending on if a mecha is popped. For the Americans, think of it as cornhole but with more kaboom. It's a lot of fun to play and it's the second most played sport in Colombia after football. In my family it's quite common for a group of us to go play tejo and drink beer just for funsies on any given afternoon.
I think the name fits the agent quite well considering that three of his abilities are explosive related (two grenades and one explosive airstrike). And of course, bringing a little attention to a sport I love is more than welcome.
