River Play

[MrFeelNothin]

Party 3/6, table is 5handed at this point.

Button is aggressive and slightly loose preflop, rarely entering a hand without raising, loose and passive postflop, going to showdown too often.

BB is new, no reads.

The BB had 7.50 left before the river, so his river bet put him all-in except for 1.5. Is this play standard? Correct? Incorrect? I won't go into my thoughts on it, rather I will see what all you all think. Thanks. Also, on a side note, should I have bet the turn?
