A name for those that frequent online chess site forums and are known for their lack of wit and small mindedness. Often those in their presence will note a foul odor, usually a result of halitosis, but if nearing the end of the month it will be due to not having showered. Upon being interviewed, women who have made the mistake of sharing a bed with a hennybogan tell of disappointment and remark upon the frequent episodes of crying. Is also becoming synonymous with flatulence and bad sex, I.e., "Aww man, someone just dropped a hennybogan!" and "That guy last night was so bad, such a hennybogan".
"I slept with a hennybogan last night, it was devastatingly bad"

"Dude, you smell like a hennybogan, what's that about"

"I met a guy last night, all he did was complain about how small his penis was and cry, what a hennybogan".
