An old-school Aussie slang word, refering to ones ability to take on another in a challenge (usually a fight).
"If you wanna be a fuckarse, I'll accommodate ya!"
"He couldn't fight his way out of a wet paper bag. I accommodated him no hassles"
When a partner wears the accomodator (an oral sex device consisting of a rubber penis which is strapped onto ones chin) and uses it on one or more partners. It may be inserted in a vagina, a butt hole, or an oral recipient. Accommodation isn't for the weak.
Jim accommodated Jan's butthole last night. Shit got intense.
