The word 'stripier' is derived from 'stripe' (from Middle English *stripe*, meaning a long, narrow band or line) and the suffix '-er' (meaning one who). Thus, 'stripier' refers to something that has more stripes or is characterized by stripes.
Think of 'stripe' as a long line or band, and remember that 'stripier' means having more of those lines.
