Boston is the act of receiving head. Usually used in a phrase, "a trip to Boston". After getting said fellatio, you would tell your homies about it subtly, with class. Possible New-York thing, not sure tho.
"Yo What happened with shawty you left with last night?"
"We went to my car and I took her on a one way trip to Boston"
"Ayyyy my nigga!"
Boston (a name) is a very sweet, kind, funny, loving person. He always knows how to make you laugh when your down and makes sure your okay. He can be dramatic sometimes but will get over it fast. He holds a strong grudge and if someone dies something he doesn’t agree with to you he will hold a grudge against them too. BOSTON IS THE BEST PERSON IN THE WORLD! Boston is a great bestfriend!
