Coño literally means "cunt/pussy" but it is very rarely used with such meaning outside of Spain. Its use is mostly associated with Spanish, Cuban, Dominican, and Puerto Rican talk as an accentuated expression equivalent to "damn", "whao", or "hell". It is not formal but not considered much vulgar either. Some parts of Latin America almost never (if ever) use this term. It is almost never heard in Mexico or cetral Colombia for example. In exchange the most employed slangword for "pussy" through Latin America is "chocha".
Cubans in particular may also abbreviate it to "ñoo" when used alone, equivalent to USA's slang "daaaium" or "deeeeim".
"Concho" is a distorted softer version as "darn it".

A sunburn or suntan focused on the left arm. It is caused by the left side of the body being the only half that gets exposed to sunlight while driving. Presumably, it would be located on the right side of the body in countries where they drive on the left side of the road.
I had a trucker's tan after driving for 10 straight hours on a sunny day.
