look up any word, like bukkake:
 
1.
parolo or parolito - comes from the spanish word parar or parado which means to stand upright or standing.

It is a common Colombian slang term for "a woody" or "an erection". The -ito is added after dropping the -o to make it less offensive or more formal if you will, however there is nothing formal about the term at all!

It is also used as a verb and not a noun as commonly referred to in English, I have a woody or I have an erection. In Colombian Spanish we would say I am wooded (if you make the literal translation from English to Spanish using the correct verb tense)
Hoy amaneci parolito.
Tengo Parola.
Ese man esta todo parolo.
