How to tell kung kayo na
Via Psychicpants, I got the link to Hickypox's funny blog entry on How to tell kung kayo na:

Dalawa kasi yan, either yung a) mag-on by mutual declaration, or b) mag-on by mutual non-declaration (mag-un or MU).


A. Mag-on by mutual declaration. Also has two variants.

1. Spontaneous mutual declaration.

Ex. A and B have knows each other for years. A and B might someday mutually decide to take their friendship a notch higher by entering into a romantic relationship, despite the fact that A and B are, respectively, a Catholic priest and an 11-year old boy.

2. Courtship - involves wooing young, parasol twirling, frilly fan fanning lasses through song and poetry, usually, with the end view of marrying said lass.

Ex. C has been courting D for several years now. One day, C threatens to explode his own head should D continue to act coolly indifferent to his advances. C acquiesces begrudgingly, faints.


B. Spontaneous mutual non-declaration

Consists of vague bilateral signals culminating in ambiguous non-promise of mutual fidelity. Set-up attractive to trendy couples keeping in step with the modern "American" style of dating. Also attractive to people not particularly demonstrative about their feelings, and to limbless mutes.
