When a girl has sex with someone and the boy cums inside her and then she puts off having a shower for a few days leaving traces of cum inside her which makes her a Curdler.
'Oh that girl smells of cum...she must be a Curdler.'

'That girls a Curdler, she had sex with Tom at that party on friday night and she still hasn't had a shower and its sunday!!'

When you brew a big shottie or bucket and the smoke is so thick that it looks like it's "curdled".
I brewed up this proper curdler bucket last night and it was flat out.
