To throw up violently - as described in the viral video hit "Gap Yah". Usually, the recounting of such a "chundering" will be punctuated by a great many less-than-savoury details on the subject.
"Yesterday, I was led out onto the parade ground... and then I just CHUNDERED EVERYWHERE, we'd been on the lash the night before."
1) A really shitty concrete curb or ledge used for grinding tricks on skateboards.
2) A very ugly/hideous face or body.
3) Anything that appears gross, deformed, unsanitary, etc.
1) I tried to nosegrind that fuckin' ledge, but I wouldn't even move cuz the shit's so chudded.
2) Dude, look at her face...that bitch is chudded. *Vomit*
3) I wouldn't eat that food even if you gave me a blowjob...look at it...it's fuckin' chudded.
In kayaking, rafting, canoeing, and catarafting when a person and/or their craft is thrown about violently in a hydraulic feature of a river for a long time. Long time, being a relative term referring to longer than you can handle, which can be less than 15 seconds. Usually the craft is recirculated back into the hole several times, leading to a feeling that escape is impossible. Characterised by a complete loss of perspective with respect to the world and commonly followed by a swim.

Dude did you see that punterraft get chundered in hellhole.
