Gravel / Gravé / Gnarmac / Groad / ATB

Just look at it this way:

• people on fancier gear who are not as fit/skilled/tough as you are are suckers with more money than sense - just laugh at them, overtake them up hills and then low-ball them for second hand parts
  
• people with fancy gear who are proportionally fitter/more skilled than you are putting their money to good use - much like one wouldn't get angry when comparing their gear/fitness to a pro, you just aspire to match/beat them one day
  
• people who are the same fitness/skill as you on fancier gear are bastards - if you beat them you make them look bad, if you lose you just blame the equipment.
