anal crap
The other definition is complete shit..."anal crap" for that matter. The person who posted it should be ashamed cause they're a f***ing moron. An oxymoron is a combination of contradictory terms (e.g. deafening silence or hopeful pessimists) which still makes sense somehow. Anal crap is just an example of redundancy (since where else would crap come from except your anus?)just like "huge giants". Repeat: other definition is "anal crap"
Who gives a shit? You're not going to use it in a normal conversation...
