to drink a couple of beers, or enough
liquor to get you to the first stage of drunk...to start feeling the alcohol.
at that point you obviously drink more to
surpass buzzed status.
this can also be used for weed...getting a little high, as opposed to getting ridiculously stoned.
"yo man i'm
feelin' stressed, wanna catch a buzz with me?"
"if i
drink this whole
40 oz i'm definitely going to catch a buzz!"
