"A person is guilty of disorderly conduct if, with purpose
to cause public inconvenience, annoyance or alarm, or recklessly creating a risk thereof, he:
"(a) engages in fighting or threatening, or in violent or tumultuous behavior; or . . .
"(c) creates a hazardous or physically offensive condition by any act which serves no legitimate purpose of the actor" (emphasis supplied in Feigenbaum).
The Commonwealth argues that the evidence supports both sections of the definition - the defendant's actions constituted tumultuous conduct and also created a hazardous condition by acts which served no legitimate purpose of the defendant.
1. Tumultuous behavior. Turning to the ordinary dictionary definition, we find that "tumultuous" is defined as "l: marked by tumult: full of commotion and uproar: riotous, stormy, boisterous . . . 2: tending or disposed to cause or incite a tumult . . . 3: marked by violent or overwhelming turbulence or upheaval." Webster's Third New Intl. Dictionary 2462 (1993) [Note 5].
