A male of a non Thai background (farang) who pays (sin sod) to a Thai pootanas parents for they're daughters hand in marriage. These men are generally referred to as big malakas and many end up not only with a massive head ache for the duration of the marriage but also paying through the nose keeping the Thai pootana and her parents comfortable, if at some stage the parents require a new house or car, the Thai pootana may be told, not asked, to dump her current farang and find a new sin sod paying farang who will fund this.
Michael: That Thai pootanas parents are asking for an exorbitant amount of money so I can marry they're daughter. Paul: You want to be a sin sod paying farang? !!! Your a big malaka, with the big money they're asking you can plug a hell of a lot of different paid pootanas for many years with less headache. You marry that pootana and I don't want to know you.
