Prone to or given to frequent, elaborate gesticulation; very expressive with hand and body movements.
From 'gesticulate' combined with the suffix '-arious' (a variant of '-ary' meaning 'of or relating to'). This rare, ornate adjective emphasizes the tendency toward extensive gesturing.
'Gesticularious' is such a fancy, over-the-top word that using it to describe someone's animated talking style is actually perfect—the word itself gesticulates!
