The traditional custom is to wrap C4 around oneself (one layer should do it, however, the more plastic explosives you lay on the more your chances of pleasing that 'special someone' increase) and to then approach the man/woman as though you are approaching a wild ram in the mountains of Chechnya; forcefully, but with loving intentions.
After he/she has acknowledged one's presence, you have to grab them by the hand so that it is difficult for them to distance themselves from you, as they may be a little bit surprised. When you have taken hold of your preferred mate, in a tender fashion persuade them to repeat the shahada after you. After you have made sure they have taken on Islam with a sincere heart, take off your bomb vest and throw it at the Polish passers-by on the other side of the road.
Making sure there are no witnesses, make your way back to Pakistan with your newly acquired Polish wife and sit her down in the family harem next to the other three.
