No it’s not a snippet from the “Alien” movie franchise it’s one of billions of Plane tree trichome on each tree! 
Due to its shape and texture it is the most irritating in the world others with less of an irritating shape are only found in rain forests! 
More good news unlike other trees trichomes their trichomes just break away easily in our air by the millions and billions and if we’re lucky some of their fungal disease and vehicle carcinogens can be combined🤮. 
And even more good news unlike other trees trichomes they are dry and rigid so they really dig into your throat and lungs😮‍💨.
