look up any word, like pussy:
 
1.
The interval of time between when one sees lightning and when one hears the thunder clap.
You can tell how far away the lightning is by counting the svaha. Each second is about 1100 feet of distance from you because light travels at the speed of light and sound travels at about 750 miles per hour (or 1100 feet per second).
