What is the 'disgusting thing'?
If you mean "where did she get that term from?", "disgusting thing" is found in the following Gospels:
Matthew 24:15-22 15
"Therefore, when YOU catch sight of the disgusting thing that causes desolation, as spoken of through Daniel the prophet, standing in a holy place, (let the reader use discernment,)
16 then let those in Ju·de´a begin fleeing to the mountains.
17 Let the man on the housetop not come down to take the goods out of his house;
18 and let the man in the field not return to the house to pick up his outer garment.
19 Woe to the pregnant women and those suckling a baby in those days!
20 Keep praying that YOUR flight may not occur in wintertime, nor on the sabbath day;
21 for then there will be great tribulation such as has not occurred since the world’s beginning until now, no, nor will occur again.
22 In fact, unless those days were cut short, no flesh would be saved; but on account of the chosen ones those days will be cut short.
Mark 13:14 14
"However, when YOU catch sight of the disgusting thing that causes desolation standing where it ought not (let the reader use discernment), then let those in Ju·de´a begin fleeing to the mountains.
How this "disgusting thing" is interpreted depends on which Doom-saying Christian you speak to. Judging from her response, your housemate is unlikely a JW.
