A fuzzy woodland creature that happens to be horny all the time, so watch out if you happen to pass by one while you're alone. These horny bastards don't descriminate against gender, so everyone has to keep an eye out. Oh, and in other cultures their other name is "Alex"
-Dude, I need to go take a piss
-Hurry up man, oh, and watch out for those squirrels
Those little furry bastards that dart out into the road when you're tryin to change the radio station, thereby causing you to swerve your car, narrowly miss that innocent tree and hit the yard full of kids play lawn darts...
"Damn, look what that fuckin squirrel made me do..."
