A belicoso is a small pointed cigar: robusto-ish length, a head that tapers to a cuttable tip. It is a figurado. Some factories treat it as a short torpedo; some as its own mold. The pointed head is the identifying fact.
You cut less of the tip than you would on a round cap if you want to keep the shape. Cut too much and you have made a parejo the hard way.
The word means bellicose. It is a name, not a strength rating. For other shaped cigars see perfecto and figurado.
