A shot of Jameson dropped into a glass of orange juice, taken in bomb form. Very popular in Chicago.
Round of Jamosas for me and my friends bar keep.

When your standard Mimosa just isn't going to cut it and you need to add a shot of Jameson to it.
After seeing the girl I hooked up last night, a standard mimosa just isn't going to cut it, I'm going to need a stiff Jamosa ASAP.
