There is a label for old men - D.O.M - Dirty Old Man. But little is known about D.O.C, the Dirty Old Chee.
If you're reasonably young and neat-looking, look out for DOC when you're at the foodcourts. If you're observant enough, you would notice that sometimes a DOC would purposely come and share a table with you even though there are many empty seats and tables around. The same with seats on the buses. But nowadays, because there area seats reserved for old folks which are located at the front section, you're less likely to come across such DOC who would skip the front section to share a seat with you.
