what would “pap jam ger lot” mean? (not sure if I spelled it correctly)

It's probably spelled "pa'p janm gen  lòt" or with the contracted indefinite article 'yon', "P'ap janm g'on lòt" contraction for "P'ap janm gen yon lòt" which means in English  "There will never be another one".

P'ap janm gen lòt tankou l.
There will never be another like him/her/it.


P'ap janm g'on lòt tankou w.
There will never be another like you.
