A leg boner occurs when one's legs stiffen, usually for a couple of days, making it awkward to walk, run etc. It is most likely to affect a person when their significant other / crush is nearby.
The most scenario of a leg boner environment is a sporting activity, with the s/o or crush in the same team as them.
