'Coercing' is a strong word and should not be used unless it is assured that it has happened
Coercing = 'persuade (an unwilling person) to do something by using force or threats'
I have seen the video myself and would not call what they did as "using force or threats" to the girl to drink (please go and search up the video to check it out yourself). and just a reminder, it is a common act for a 'drinking party' to offer and encourage drinking as to lighten the mood of the situation.
and most of all, people should understand that tabloid magazines and many other related media would try to use words that would appeal to people's interest.
But then regarding the age issue, they have said that they have been told they are of the correct age to drink, whether this is true or not I don't know but there is a 50/50 chance for this
