Monhus this is a word when you cannot say any word and your speech less so you use this word to shut down that question or a sentence since they don't know what it means
When yer doin' yer bitch and it's pretty intense and you can feel yer gonna empty yer nutsack any second and all of a sudden yer bitch screams and yer thinking that it's just a noisier than usual shegasm but then ya see somethin' fluttering about and ya see this dark object on her right breast and it turns out that she's freakin' out about a moth and the whole episode puts a (temporary) damper on the two of ya gettin' off.
It seemed my bitch's vajayjay was close to creamin' and I was thinkin' I'd soon be gettin' back to watchin' monster truck madness when a sudden case of mothus interruptus made me have ta start pleasurin' the ho all over again ...Dang!
