A Jugasaurus-Rex is the name given to a
female with extremely large
breasts.
The phrase was made famous by Neil from t.v
show 'The Inbetweeners' where he spots a girl in the park and says, 'Hey guys, look at that Jugasaurus-Rex!'.
'Hey Lewis, Jugasaurus-Rex at
5'o'
clock!'
'Woah, Your a right Jugasaurus-Rex!'
'
Don't you think that Pamella Anderson is just one huge Jugasaurus-Rex?'
