Thought this might be a fun thread...here's my list:
1.
Introduce him to your whole family. Make sure that you give your family
a heads up that they should be overly affectionate, hug, and say
"Welcome to the family!"
1a. Tell them about how much you've always loved them. Propose.
2. Talk about your ticking biological clock. Ask if he/she wants a large family
3. Talk about marriage
4. Talk about your ex--ad nauseaum. Talk in extremes--either how much you loved them/hated them. DO NOT be neutral.
5. Talk about your sex life/lack thereof
6. If you had offered to pay for dinner--come up short on the bill--accuse them of ordering/eating too much.
7. If you offered to pay--shoot them a look and tell them not to order
the most expensive thing on the menu. When they order, cut them off and
tell them that it's too much.
8. Drink too much. Get sloppy drunk.
9. Show up for your date already high, drunk, etc.
10. Don't shower/bathe before your date. In fact, go to the gym and walk the dogs/do yardwork, etc. and then go on your date.
11. Talk about your medical/hygiene issues--like foot odor, b.o., constipation, etc.
12. If you actually make it to a kiss, make it a wet and sloppy one--be aggressive--shove your tongue down their throat.
13. Suggest in a not-so-subtle way after the date that you expect them to 'put-out' especially if you have paid.
14. Curse
15. Talk about hot-button issues--abortion, religion, etc. Disagree
with whatever they might say--disagree in a disagreeable way...
