Is this tape sticky enough to stay on that surface?
Potentially difficult to escape from.
This is a sticky situation. We could be in this for weeks if we're not careful.
Of weather, hot and windless and with high humidity, so that people feel sticky from sweating.
(of a setting) Persistent.
We should make the printing direction sticky so the user doesn't have to keep setting it.
(of a window) Appearing on all virtual desktops.
(of threads on a bulletin board) Fixed at the top of the list of topics or threads so as to keep it in view.
(of a website) Compelling enough to keep visitors from leaving.
A woman has come to me with the complaint that her website is not sticky: 70% of the visits last 30 seconds or less.
