Wombo Combo
The Wombo Combo refers to both a combo and a video from the competitive Smash community. The video itself refers to a Californian tournament with commentary by HomeMade Waffles, Phil, and Mango in response to an accidental combo started by SS and Tang against Mango.
Origin
The Wombo Combo was "accidentally" created on Battlefield by SS (Captain Falcon)/Tang (Fox) and used on Zhu, who was playing as Fox. The original move itself was by using a constant grab release, until a final three-hit move of the Reflector, up smash, and then a knee smash to win the match for SS/Tang. The combo put Zhu's damage from 0 all the way to 77 percent.
The combo video later became extremely popular in other communities on the Internet, not just the Smash community; this is due to the video's humorous reactions that can be partially applied to a wide variety of other games, coining such phrases as "That ain't Falco!", and "Get yo ass whooped!". The sound has since been applied to other combos where it is usually coupled with the commentary to give the video humor value. A modified "You mad 'cause I'm stylin' on you" video was later uploaded with commentary from the Wombo Combo video, where Mango, Phil, and HomeMadeWaffles yell their signature quotes as a fight breaks out when the talking man opposite the one in front of the camera is punched.
"Sequels" to the Wombo Combo
Wombo Combo 2
A later satire of the Wombo Combo by SS and Tang vs. Phil + Falcomist on Corneria which had a large 19 to 86 right after HMW said "Wombo combo" again. The tournament that this event was taken was in the CGC @ SFSU IX(9) (Bi-Weeklies) Grand Finals 2.2 in San Francisco, CA. The date that this was taken was 05/02/09. The commentry was by HomeMadeWaffles and Replicate.
The sequel is the only Wombo Combo video to not take place on Battlefield.
Lunch Money Combo
The lunch money combo was with SS/Tang vs Shroomed/D.P at the Battlefield (the same stage as the original Wombo Combo). The combo was a 0 to 71 on D.P's Falco. The tournament that this event was taken was in the CGC @ SFSU XIII(13) Winners Finals 1.3 in San Francisco, CA. The date that this event was taken was 11/7/09. The commentary was by HMW and Darrell.
The UGS combo
Commonly considered the European version of the Wombo Combo, done by Armada (Peach) and Aniolas (Sheik) on a Falco on Battlefield (referencing the quote "That ain't Falco!" from the original video). A remixed video was later made, featuring audio from the original Wombo Combo video.
