A woman engaged in conversation at a cocktail party cuts loose with a hisser, i.e., she silently passes gas. She will usually try to affect an air of bored nonchalance but, to deflect possible attention to herself, will often transfix the nearest male with an accusatory glare which implies, 'You pig! How dare you do that in my presence?'
Hell emo person that hangs in the city and hisses at people. Emotional, clingy and only associates in small negative groups. Cartoon characteristics that physically represent feelings, little over exaggerated hand movements. Acts like a baby, cute but scary ways.
Looks at those hissers sitting in a group at the park in the city, cuddling and making baby noises. Look at their facial piercings
