Meaning:

    “前方” means “ahead,” and “高能” means “high energy.” The phrase first appeared in “Mobile Suit Gundam,” an online games developed by Japanese company Namco Bandai Games. While the fleet marches in outer space, the scouats will detect changes in energy in the front and high energy will indicate possible strong attacks from the enemies. In that case, the scouts will remind spacecraft captions of their own army to make preparations or dodge the attacks. Chinese netizens use the term to remind people of something exciting or unusual in the sequences to be shown in a video or movie. It’s also used generally to remind people of something exciting or terrible that will happen. Therefore, it’s the joking way to say “Watch out!”
