Lag
From Tootsville Wiki-Wiki
“Lag” is the delay in a network.
It's like sending postal mail: if you send a letter a far distance, it will take longer to arrive than someplace nearby.
Routing on the Internet is very complicated. It's hard to guess how your data will travel to get from one place to another.
If your “lag” to other mesh networking users is very high, the game may start acting weird or “jumpy.” The Gossip Mice will probably try to offer you advice.
