Boston Shot Glass 

When a bloke jizz's into a shot glass and then inserts in in her vagina

Double Boston Shot Glass 

Just like the Boston Shot glass: where a bloke jizz's into two shot glasses and one is inserted in her vagina and the other shot glass is inserted into the arsehole of your partner.

G: Hey Bakes, I gave your grand mother a double boston shot glass.

B: Really?

G: Yeah! I didn't know she could say cheers.
