look up any word, like pussy:
 
1.
210
The San Antonio Area code. And since its also a term for blow job I guess it makes us a bunch of sluts.
Come to San Antonio for a 210 because that's our area code.

2.
210
code word for a blow job (aka bj, felatio, oral, "going down", two-ten). "b" is the 2 and "j" is the 10, by the order of letters in the alphabet.
"Hey guess what?"
"What?"
"My girlfriend's giving me a 210 after school!"
"No she's not! Wait-you don't even have a girlfriend!"
"Yeah... I know."
"Plus I thought you were gay!"
