A deep thunderous roar of raging testosterone, occurs when one surpasses the point where words can accurately express their fury. The sound of a man bellowing with rage, a warcry if you will. Something you'd hear shortly before receiving a fist to your face. Only a real man can procure a true WOARRR. Emitted from the very core of one's rage, it will shatter the self-esteem of a woman instantly as she realises physical oblivion is nigh. If you hear this sound be aware of the source, as it's likely to be followed up by a knuckle sandwich.
The noise a woman (or man) makes when engaging in noisy fellatio; specifically in "deep throat" situations where the person receiving is making vocal noises from the throat which are repeatedly interrupted by the obvious and frequent obstruction.
