An underdog is something that always seems to be trailing behind, but not always as bad as what’s more popular. Often times when an underdog becomes more know, people new to it tend to cram it down your throat and preach to you how much better it is then everything else. They will also go on Urban Dictionary and write definitions about how great it is, and trash everything else.

OMG everyone says FireFox Ownz, and its the underdog also, so it must be good. Anyone who doesn't have Firefox is a stupid nubzor. All you little nub kids need to get it now! I don't even know why it's good, everyone else told me it was.

When someone or something that's expected to lose, but later, they became the winner.
"I didn't expect that the other team won, they had only 2 points, what an underdog!"
"The red side was out numbered and think they were going to lose, but somehow, the blue team caught up and win the battle! They're the underdog!"

An old expression from the Australian bush. Before sawmills made their appearance, felled logs were dragged to a saw-pit and cut lengthwise into planks by two men using a cross-cut saw, a mean beast of a thing up to 10 feet long. One man would stand on top of the log and push down, and the man underneath standing in the pit - the underdog - would push the saw up.

A rotten job, with sawdust in your eyes all day and really hard work compared to the top dog who just had to push the saw down. The boss never saw how hard this man worked, so he was less likely to get a better job, a pay rise or be noticed at all.

Now an underdog is someone - or something which is going to struggle against superior odds to win a contest.
The new Vegetarians Party will always be the underdog in Texan elections.
