Derived from combining the words, "Yak" and "Burp". One who "yurps" is typically one who physically cannot burp. Yurps usually occur after consuming copious amounts of brew. Most often, the "yurper" will release the yurp above a sink, toilet, or garbage to be safe. Yurps naturally sound like a cross between a harsh belch and a dog coughing up last night's dinner scraps.
"Dude, I think he's yakin' in your bathroom"
"Nah guys relax, he's just lettin' go some yurps."
"Awhh, good for him."
