Olympic TV announcers: Go Russia! Booooo USA!

As the young Olympic gymnast competed in the all-arounds, the TV announcer said: "She messed up really well. This is so good, she got another deduction of points."

Not the type of attitude you'd normally expect from a TV sports commentator. Unless the announcer is Russian, and the athlete is an American.

Though every country's commentators undoubtedly want their respective nations to win, nowhere is that more clear than in Russia—the host country of this year's Winter Olympic games in Sochi.

If the London Olympics are any indication, not only do the Russians want their athletes to win—just as importantly, they want the Americans to lose.

During the all-around women's gymnastics competition, former Olympic champion and gymnast Lidiya Gavrilovna Ivanova provided commentary for Russia's "Rossiya-2 Sport" Channel.

Before Russian gymnast Viktoria Komova did her vault, Ivanova announced: "Vikochka (sweet Vicky), show these Americans how it should be done."

After Komova made mistakes in her routine, Ivanova remarked with: "She made a few mistakes, but we did not notice them."

Ivanova was particularly disgusted with U.S. Olympic champion Aly Raisman. When Raisman nearly lost her balance on the beam, Ivanova quipped: "I'm watching for her to mess up again."

U.S. allies are not exempt from Russian announcers' scorn. When the U.K.'s Elizabeth Tweddle took to the floor, Ivanova said, "Show them your crooked legs, Beth."

Fellow commentator for Rossiya-2, Dmitry Bobtsov, informed the audience that they should not bother watching one of the award ceremonies since the American national anthem would be played:

"We won't listen to the American anthem, there's no point," he said.

Bobtsov also referred to some of the men on other countries' gymnastics teams as "pieces of wood," claimed that the Americans were "showing off" and referred to American Olympic gymnast Jonathan Horton as "little legs, little arms, and ugly."

Both commentators were in agreement that the Americans "unfortunately" did well, but that the judges still gave them much higher scores than they deserved.

Russian announcers' vitriol isn't limited to gymnastics, but is more prevalent among events that are subjectively scored by judges, such gymnastics and figure-skating.

During the London games, even Russian fans were surprised at how partisan, to say the least, their commentators were.

Many Russian Olympic fans responded to the commentators online by saying they were "embarrassed" by them. One fan wrote, "I haven't seen such open hatred toward the American athletes and such obnoxious behavior by the commentators in a long time."

Another viewer wrote: "Dear commentators, how much hatred you have towards people who have worked just as hard and wanted to win. It is embarrassing and annoying to listen to you."

Now that the games will be in Russia, the pressure is on for the host country to take home the gold in a number of Olympic events.

Russia's commentators are ready to take their posts, and we'll be watching for how they take the wins—and the losses. Come back to CNBC.com for more as the games unfold.
